Following the development of organic mechanoluminescence (ML) materials, mol. packing was proved as the key point to the emission process under an external force. In this text, with the introduction of spiro-(fluorene-9-9′-xanthene) (SFX) unit as the building block, the mol. packing of the resultant compound (BSFXA) was optimized with the interlaced mode, directly leading to the efficient ML effect. The key role of SFX with a spiro-structure can be further confirmed by the ML inactivity of reference compound BFA with the replacement of SFX unit by di-Me fluorene (MeF), which provided a novel strategy to construct organic ML luminogens. The results came from multiple reactions, including the reaction of Bis(4-methoxyphenyl)amine(cas: 101-70-2Application In Synthesis of Bis(4-methoxyphenyl)amine)

Safety of Bis(4-methoxyphenyl)amineIn 2019 ,《Introduction of Fluorine Into spiro[fluorene-9,9′-xanthene]-Based Hole Transport Material to Obtain Sensitive-Dopant-Free, High Efficient and Stable Perovskite Solar Cells》 was published in Solar RRL. The article was written by Guo, Kunpeng; Wu, Min; Yang, Shaomin; Wang, Zongtao; Li, Jie; Liang, Xiaozhong; Zhang, Fang; Liu, Zhike; Wang, Zhongqiang. The article contains the following contents:

Despite the substantial development of efficient hole transporting materials (HTMs) for high-performance perovskite solar cells (PSCs), optimization of the HTMs to sensitive-dopant-free HTMs for high efficient PSCs with prominent stability have rarely been reported. Herein, a low-cost fluorinated spiro[fluorene-9,9′-xanthene] based HTM termed 2mF-X59 is designed and synthesized. In comparison with its reported nonfluorinated counterpart X59, 2mF-X59 shows lowered HOMO (HOMO) level, improved hole mobility, and hydrophobicity. Aided by 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) to further lower the HOMO level of 2mF-X59 and improve its hole transfer, the optimized 2mF-X59 based PSCs show a maximum power conversion efficiency (PCE) of 18.13% without the use of any sensitive-dopants (e.g., lithium salt/4-tert-butylpyridine), which is comparable to the Spiro-OMeTAD based PSCs (18.22%) with sensitive dopants. More importantly, the sensitive-dopant-free 2mF-X59 based PSCs maintain 95% of their initial performance for more than 500 h under air exposure, showing much better long-term stability than control PSCs based on Spiro-OMeTAD with sensitive dopanst. This is the first case that a sensitive-dopant-free HTM is demonstrated in PSCs with a high PCE (>18%) and good stability by optimizing the literature HTM. This work could pave a new way to develop low-cost sensitive-dopant-free HTMs for highly efficient and stable PSCs for practical applications.

The article was titled 《Double-Helicene-Based Hole-Transporter for Perovskite Solar Cells with 22% Efficiency and Operation Durability》. The information in the text is summarized as follows:

Amelioration of the mobility and, in particular, the thermal stability of a hole-transporting mol. semiconductor is a practicable strategy to attain the enhancement of both power conversion efficiency (PCE) and operational durability of perovskite solar cells (PSCs). Here, a cost-effective double-[4]helicene-based mol. semiconductor (DBC-OMeDPA) is synthesized for a solution-deposited thin film, exhibiting an improved hole mobility in comparison with state-of-the-art spiro-OMeTAD control. X-ray crystallog. anal. and theor. calculation reveal the 3-dimensional mol. stacking and multidirectional hole-transporting property of DBC-OMeDPA, clarifying the microscopic mechanism of the hole-transport process. A better PCE of 22% at the AM 1.5G conditions is achieved for PSCs with DBC-OMeDPA as the hole-transporter. PSCs using DBC-OMeDPA characteristic of an elevated intrinsic glass transition temperature of 154° maintain a stable PCE output for hundreds of hours at 60° under equivalent full sunglight soaking.Bis(4-methoxyphenyl)amine(cas: 101-70-2Safety of Bis(4-methoxyphenyl)amine) was used in this study.

Rosendale, Morgane’s team published research in Molecules in 2022 | CAS: 101-70-2

In 2022,Rosendale, Morgane; Daniel, Jonathan; Castet, Frederic; Pagano, Paolo; Verlhac, Jean-Baptiste; Blanchard-Desce, Mireille published an article in Molecules. The title of the article was 《Stealth Luminescent Organic Nanoparticles Made from Quadrupolar Dyes for Two-Photon Bioimaging: Effect of End-Groups and Core》.Quality Control of Bis(4-methoxyphenyl)amine The author mentioned the following in the article:

Mol.-based Fluorescent Organic Nanoparticles (FONs) are versatile light-emitting nano-tools whose properties can be rationally addressed by bottom-up mol. engineering. A challenging property to gain control over is the interaction of the FONs′ surface with biol. systems. Indeed, most types of nanoparticles tend to interact with biol. membranes. To address this limitation, we recently reported on two-photon (2P) absorbing, red to near IR (NIR) emitting quadrupolar extended dyes built from a benzothiadiazole core and diphenylamino endgroups that yield spontaneously stealth FONs. In this paper, we expand our understanding of the structure-property relationship between the dye structure and the FONs 2P absorption response, fluorescence and stealthiness by characterizing a dye-related series of FONs. We observe that increasing the strength of the donor end-groups or of the core acceptor in the quadrupolar (D-π-A-π-D) dye structure allows for the tuning of optical properties, notably red-shifting both the emission (from red to NIR) and 2P absorption spectra while inducing a decrease in their fluorescence quantum yield. Thanks to their strong 1P and 2P absorption, all FONs whose median size varies between 11 and 28 nm exhibit giant 1P (106 M-1.cm-1) and 2P (104 GM) brightness values. Interestingly, all FONs were found to be non-toxic, exhibit stealth behavior, and show vanishing non-specific interactions with cell membranes. We postulate that the strong hydrophobic character and the rigidity of the FONs building blocks are crucial to controlling the stealth nano-bio interface. After reading the article, we found that the author used Bis(4-methoxyphenyl)amine(cas: 101-70-2Quality Control of Bis(4-methoxyphenyl)amine)

Reference of Bis(4-methoxyphenyl)amineIn 2019 ,《Synthesis, photophysical and electronic properties of tetra-donor- or acceptor-substituted ortho-perylenes displaying four reversible oxidations or reductions》 was published in Chemical Science. The article was written by Merz, Julia; Steffen, Andreas; Nitsch, Joern; Fink, Julian; Schuerger, Claudia B.; Friedrich, Alexandra; Krummenacher, Ivo; Braunschweig, Holger; Moos, Michael; Mims, David; Lambert, Christoph; Marder, Todd B.. The article contains the following contents:

(DPA)4-Per I and (Bmes2)4-Per II derivatives were synthesized via regioselective Ir-catalyzed C-H borylation and subsequent reactions, a strong π-donors and acceptors at the 2,5,8,11-positions of perylene were introduced leading to unusual properties. Thus, incorporation of four donor diphenylamine (DPA) or four acceptor Bmes2 (mes = 2,4,6-Me3C6H2) moieties yielded novel compounds which can be reversibly oxidized or reduced four times, resp., an unprecedented behavior for monomeric perylene derivatives Spectroelectrochem. measurements showed NIR absorptions up to 3000 nm for the mono-cation radical of II and a strong electronic coupling over the perylene bridge was observed indicative of fully delocalized Robin-Day Class III behavior. Both derivatives I and II possess unusually long intrinsic singlet lifetimes (τ0), e.g., 94 ns for the former one. The compounds I and II were emissive in solution, thin films, and the solid state, with apparent Stokes shifts were exceptionally large for perylene derivatives Transient absorption measurements on II revealed an addnl. excited state, with a long lifetime of 500μs, which sensitized singlet oxygen effectively.

Chen, Yung-Chung’s team published research in Solar Energy in 2019 | CAS: 101-70-2

In 2019,Solar Energy included an article by Chen, Yung-Chung; Yen, Jui-Hua; Chung, Chung-Lin; Chen, Chih-Ping. Category: ethers-buliding-blocks. The article was titled 《Methoxy groups on bifluorenylidene-based hole transporting materials result in highly efficient and stable dopant-free inverted perovskite solar cells》. The information in the text is summarized as follows:

Three bifluororenylidene-based compounds featuring different numbers of methoxy groups (none for HTM-1, four for HTM-2, and eight for HTM-3) have been synthesized simply and inexpensively and applied as hole transporting materials (HTMs) in inverted perovskite solar cells (PSCs). For comparison, a typical inverted HTM material, PEDOT:PSS, was also applied in a corresponding inverted PSC. The corresponding cell performances were compared with respect to their number of methoxy groups. Of the PSCs containing the bifluororenylidene-based compounds, the HTM-2-based device exhibited the highest power conversion efficiency (PCE) of 12.0%, with a value of Jsc of 19.4 mA cm-2, a value of Voc of 0.94 V, and a fill factor of 65.6%. In addition, the PCE of this HTM-2-based device was higher than that (9.9%) of the PEDOT:PSS-based cell under similar testing conditions. The relatively high PCE of the HTM-2-based cell was due to its suitable energy levels, relatively high hole mobility, and relatively large grains. Furthermore, the HTM series of compounds were also more hydrophobic than PEDOT:PSS and, therefore, they imparted device stability superior to that of the PEDOT:PSS-based cell. In the experiment, the researchers used many compounds, for example, Bis(4-methoxyphenyl)amine(cas: 101-70-2Category: ethers-buliding-blocks)

Sun, Zhu-Zhu; Feng, Shuai; Ding, Wei-Lu; Peng, Xing-Liang; Guan, Jian; Zhao, Zhiqiang published an article in 2021. The article was titled 《Molecular design of dibenzo[g,p]chrysene-based hole-transporting materials for perovskite solar cells: A theoretical study》, and you may find the article in Synthetic Metals.Quality Control of Bis(4-methoxyphenyl)amine The information in the text is summarized as follows:

Designed with a steric twisted, π-conjugated dibenzochrysene (DBC) core and arylamine-based electron-donating side arms, four small mols. as hole-transporting materials (HTMs) are simulated with d. functional theory and Marcus theory of electron transfer. Our results show that, adding the fluorene moiety in auxiliary side arms and extending the π-conjugated structure can make the HOMO (HOMO) energy levels down-shifted. By tailoring of electron-donating side arms, the HOMO levels of designed HTMs range from -4.95 to -5.24 eV, which affords a chance for the interfacial energy regulation. Meanwhile, we also find that the suitable extension of π-conjugated side arms and the accessorial sulfur-sulfur interaction may be beneficial for promoting the intermol. electronic coupling. Coupled with the lower reorganization energy, the DBC-4 (7.08 x 10-1 cm2 v-1 s-1) displays the largest hole mobility. In addition, the better solubility can be expected for the DBC-4 due to the larger solvation free energy, whereas its stability may be somewhat lower. Adding thiophene unit in side arms makes the absorption spectra obviously red-shift. Overall, this work provides some useful clues for designing of high-efficient HTMs, and the DBC-4 is proposed as potential HTM.

《Online High-Performance Liquid Chromatography Analysis of Buchwald-Hartwig Aminations from within an Inert Environment》 was written by Malig, Thomas C.; Yunker, Lars P. E.; Steiner, Sebastian; Hein, Jason E.. Formula: C14H15NO2 And the article was included in ACS Catalysis in 2020. The article conveys some information:

Obtaining data-dense reaction profiles for reactions performed under an inert atm. remains a significant challenge obfuscating mechanistic anal. To this end, we have developed a reaction monitoring platform capable of automated sampling and online HPLC anal. to generate temporal profiles for reactions performed from within a glovebox. The device allows for facile reaction progress anal. to aid in mechanistic studies of air-sensitive chem. transformations. The platform has demonstrated high reproducibility regarding sample mixing, dilution, delivery, and anal. We employed the sampling platform to acquire temporal profiles for a series of Buchwald-Hartwig aminations. Parallel coupling reactions using iodobenzene and bromobenzene both exhibit complex kinetics. A competition reaction including both aryl halides demonstrated high selectivity for iodobenzene indicative of catalyst monopoly. The temporal profile for the difunctionalized substrate 1,4-iodobromobenzene was unexpected based on our parallel and competition studies and is indicative of a distinct underlying mechanism. We attribute this unanticipated reactivity to intramol. catalyst transfer through the π system as seen in “”living”” polymerization transfer catalyst systems. The use of this automated sampling platform has greatly increased mechanistic understanding despite performing only a small number of experiments In the experimental materials used by the author, we found Bis(4-methoxyphenyl)amine(cas: 101-70-2Formula: C14H15NO2)

Xu, Niansheng’s team published research in Chemical Science in 2020 | CAS: 101-70-2

《D-p-D molecular semiconductors for perovskite solar cells: the superior role of helical versus planar p-linkers》 was written by Xu, Niansheng; Zheng, Aibin; Wei, Yuefang; Yuan, Yi; Zhang, Jing; Lei, Ming; Wang, Peng. Recommanded Product: Bis(4-methoxyphenyl)amine And the article was included in Chemical Science in 2020. The article conveys some information:

Controlling the mode of mol. packing and the size of mol. aggregates is of fundamental importance for high-performance charge transport materials in next-generation optoelectronic devices. To clarify the peculiar role of helicene as a kernel block in the exploration of unconventional organic semiconductors, in this work thia[5]helicene (T5H) is doubly aminated with electron-donating dimethoxydiphenylamine to afford T5H-OMeDPA, which is systematically compared with its perylothiophene (PET) congener (PET-OMeDPA). On the basis of the quantum theory of atoms in mols. and energy decomposition anal. of single crystals, it is surprisingly found that while p-p stacking of planar PET is stronger than that of helical T5H, this desirable effect for the charge transport of organic semiconductors is completely lost for donor-p-donor (D-p-D) type PET-OMeDPA but is retained for T5H-OMeDPA to a large extent. Consequently, the T5H-OMeDPA single-crystal presents about 5 times higher theor. hole-mobility than PET-OMeDPA. With respect to PET-OMeDPA, there is a weaker electronic coupling of helical T5H-OMeDPA with perovskites, leading to reduced interfacial charge recombination. Due to reduced transport resistance and enhanced recombination resistance, perovskite solar cells with T5H-OMeDPA exhibit a power conversion efficiency of 21.1%, higher than 19.8% with PET-OMeDPA and 20.6% with the spiro-OMeTAD control.
