In this work, we assess the possible reasons for the differences observed in open circuit voltage (VOC) in mixed cation perovskite solar cells when comparing four different hole transport materials (HTMs), namely TAE-1, TAE-3, TAE-4 and spiro-OMeTAD. All these HTMs present close chem. and phys. properties, however, once they are finally deposited onto the perovskite layer, the HTMs provide different performance characteristics. Addnl. to the evaluation of the HTM influence on recombination, we find that, upon deposition of the organic HTM on top of the perovskite, there is an important change in the energy level position, and the impact on the device VOC is discussed. We consider that this exptl. observation could be general for other organic HTMs and would justify the difficulties in finding mols. and materials that could improve the efficiency of perovskite solar cells overcoming the solar-to-energy conversion efficiency of solar cells made using spiro-OMeTAD as a hole selective contact.

The article was titled 《Low-Cost Hole-Transporting Materials Based on Carbohelicene for High-Performance Perovskite Solar Cells》, and you may find the article in ACS Applied Materials & Interfaces.SDS of cas: 101-70-2 The information in the text is summarized as follows:

Two hole-transporting materials (HTMs) based on carbohelicene cores, CH1 and CH2, are developed and used in fabricating efficient and stable perovskite solar cells (PSCs). Owing to the rigid conformation of the helicene core, both compounds possess unique CH-π interactions in the crystalline packing pattern and good phase stability, which are distinct from the π-π intermol. interactions of conventional planar and spiro-type mols. PSCs based on CH1 and CH2 as HTMs deliver excellent device efficiencies of 19.36 and 18.71%, resp., outperforming the control device fabricated with spiro-OMeTAD (18.45%). Furthermore, both PSCs exhibit better ambient stability, with 90% of initial performance retained after aging with a 50-60% relative humidity at 25°C for 500 h. Due to the low production cost of both compounds, these newly designed carbohelicene-type HTMs have the potential for the future commercialization of PSCs. In addition to this study using Bis(4-methoxyphenyl)amine, there are many other studies that have used Bis(4-methoxyphenyl)amine(cas: 101-70-2SDS of cas: 101-70-2) was used in this study.

《Tetrasubstituted Thieno[3,2-b]thiophenes as Hole-Transporting Materials for Perovskite Solar Cells》 was written by Urieta-Mora, Javier; Garcia-Benito, Ines; Zimmermann, Iwan; Arago, Juan; Molina-Ontoria, Agustin; Orti, Enrique; Martin, Nazario; Nazeeruddin, Mohammad Khaja. Electric Literature of C14H15NO2 And the article was included in Journal of Organic Chemistry in 2020. The article conveys some information:

Three hole-transporting materials (HTMs) were prepared following a straightforward synthetic route by crosslinking arylamine-based ligands with a simple thieno[3,2-b]thiophene (TbT) core. The novel HTMs were fully characterized with standard techniques to gain insight into their optical and electrochem. properties and were incorporated in solution-processed mesoporous (FAPbI3)0.85(MAPbBr3)0.15 perovskite-based solar cells. The similar mol. structure of the synthesized HTMs was leveraged to investigate the role that the bridging units between the conjugated TbT core and the peripheral arylamine units plays on their properties and thereby on the photovoltaic response. A remarkable power conversion efficiency exceeding 18% was achieved for one of the TbT derivatives, which was slightly higher than the value measured for the benchmark spiro-OMeTAD. The results came from multiple reactions, including the reaction of Bis(4-methoxyphenyl)amine(cas: 101-70-2Electric Literature of C14H15NO2)

Recommanded Product: 101-70-2In 2021 ,《Tetraphenylethylene-Arylamine Derivatives as Hole Transporting Materials for Perovskite Solar Cells》 was published in ACS Applied Materials & Interfaces. The article was written by Zhang, Xianfu; Liu, Xuepeng; Ghadari, Rahim; Li, Maohui; Zhou, Zi’an; Ding, Yong; Cai, Molang; Dai, Songyuan. The article contains the following contents:

A series of hole transporting materials (HTMs) with fused tetraphenylethylene cores (9,9′-bifluorenylidene and dibenzo[g,p]chrysene) as well as different substitution positions of arylamine side arms has been designed and synthesized. A reference HTM with a non-fused tetraphenylethylene core is also prepared for a comparative study. It is noted that fused tetraphenylethylene mols. show a bathochromic spectral shift, electroneg. character, and lower reorganization energies than the non-fused ones. Furthermore, the mols. with side arms located on the meta-position on the tetraphenylethylene core in terms of a double bond exhibit a deeper HOMO level than those of the para-position-based ones whether tetraphenylethylene is fused or not. Moreover, the reorganization energies of fused meta-position-based HTMs are lower than those of para-position-based HTMs. Fused tetraphenylethylene HTMs own a better hole-extraction capability than the non-fused ones. When used in perovskite solar cells, all devices with fused tetraphenylethylene HTMs display better performance than those of the non-fused ones. The HTMs based on dibenzo[g,p]chrysene exhibit better performance than those of bifluorenylidene. Moreover, the devices with HTMs with side arms located on the meta-position on the tetraphenylethylene core display higher power conversion efficiency than those of the para-position-based ones. The results give some new insight and reference to develop ideal HTMs for perovskite solar cells.

And the article was published in ACS Applied Materials & Interfaces in 2019. Quality Control of Bis(4-methoxyphenyl)amine The author mentioned the following in the article:

A novel set of hole-transporting materials (HTMs) based on π-extended diindolotriazatruxene (DIT) core structure with electron-rich methoxy-engineered functional groups were designed and synthesized via a facile two-step procedure. All compounds were afforded from inexpensive precursors without a complex purification process. Cyclic voltammograms indicate that the resulting HTMs exhibit suitable HOMO (HOMO) energy levels, which facilitate efficient hole injection from the valence band of perovskites into the HOMO of DIT-based HTMs as confirmed by time-resolved photoluminescence. Notable power conversion efficiency of the planar perovskite solar cells with low-temperature device fabrication achieved 18.21% utilizing D2, which is competitive with the corresponding devices based on the common Spiro-OMeTAD-based HTMs. The results manifest that DIT-based compounds are promising HTMs for constructing high-efficiency planar perovskite solar cells with low-cost solution processing procedures.

The article was titled 《Upregulating Aggregation-Induced-Emission Nanoparticles with Blood-Tumor-Barrier Permeability for Precise Photothermal Eradication of Brain Tumors and Induction of Local Immune Responses》.Application In Synthesis of Bis(4-methoxyphenyl)amine The article contains the following contents:

Compared to other tumors, glioblastoma (GBM) is extremely difficult to treat. Recently, photothermal therapy (PTT) has demonstrated advanced therapeutic efficacy; however, because of the relatively low tissue-penetration efficiency of laser light, its application in deep-seated tumors remains challenging. Herein, bradykinin (BK) aggregation-induced-emission nanoparticles (BK@AIE NPs) are synthesized; these offer selective penetration through the blood-tumor barrier (BTB) and strong absorbance in the near-IR region (NIR). The BK ligand can prompt BTB adenosine receptor activation, which enhances transportation and accumulation inside tumors, as confirmed by T1-weighted magnetic resonance and fluorescence imaging. The BK@AIE NPs exhibit high photothermal conversion efficiency under 980 nm NIR laser irradiation, facilitating the treatment of deep-seated tumors. Tumor progression can be effectively inhibited to extend the survival span of mice after spatiotemporal PTT. NIR irradiation can eradicate tumor tissues and release tumor-associated antigens. It is observed that the PTT treatment of GBM-bearing mice activates natural killer cells, CD3+ T cells, CD8+ T cells, and M1 macrophages in the GBM area, increasing the therapeutic efficacy. This study demonstrates that NIR-assisted BK@AIE NPs represent a promising strategy for the improved systematic elimination of GBMs and the activation of local brain immune privilege.

The article contains the following contents:

Four spirobisacridine (SBA) hole-transporting materials were synthesized and employed in perovskite solar cells (PSCs). The mols. bear electronically inert alkyl chains of different length and bulkiness, attached to in-plane N atoms of nearly orthogonal spiro-connected acridines. Di-p-methoxyphenylamine (DMPA) substituents tailored to the central SBA-platform define electronic properties of the materials mimicking the structure of the benchmark 2,2′,7,7′-tetrakis(N,N-di-4-methoxyphenylamino)-9,9′-spirobifluorene (spiro-MeOTAD), while the alkyl pending groups affect mol. packing in thin films and affect the long-term performance of PSCs. Devices with SBA-based hole transporting layers (HTL) attain efficiencies on par with spiro-MeOTAD. More importantly, solar cells with the new HTMs are hysteresis-free and demonstrate good operational stability, despite being doped as spiro-MeOTAD. The best performing MeSBA-DMPA retained 88% of the initial efficiency after a 1000 h aging test under constant illumination. The results clearly demonstrate that SBA-based compounds are potent candidates for a design of new HTMs for PSCs with improved longevity.

Fluorescent light modulation by small elec. potentials has gained huge interest in the past few years. This phenomenon, called electrofluorochromism, is of the utmost importance for applications in optoelectronic devices. Huge efforts are being addressed to developing electrofluorochromic systems with improved performances. One of the most critical issue is their low cyclability, which hampers their widespread use. It mostly depends on the intrinsic reversibility of the electroactive/fluorophore mol. system and on device architecture. Here the authors show a novel fluorene-based mixed-valence electrofluorochromic system that allows direct electrofluorochromic switching and exhibits incomparable electrochem. reversibility and device cyclability of >10,000 cycles.

Gao, Wei-Jie; Yu, Hui-Juan; Chen, Jian; Xiao, Jing; Fang, Jing-Kun; Jia, Xiang-Rui; Peng, Chi-Fang; Shao, Guang; Kuang, Dai-Bin published their research in Chemical Engineering Journal (Amsterdam, Netherlands) in 2021. The article was titled 《Simple hole-transporting materials containing twin-carbazole moiety and unconjugated flexible linker for efficient and stable perovskite solar cells》.Product Details of 101-70-2 The article contains the following contents:

Three twin-carbazole-based hole-transporting materials (HTMs) bearing an unconjugated flexible linker and four peripheral diphenylamine groups with different methoxy positions (pp-, pm-, and po-) are first synthesized (GJ-pp, GJ-pm, and GJ-po) and successfully employed in perovskite solar cells (PSCs). The HTMs were obtained from simple synthetic steps and facile purification techniques. The thermal stability, optical and electrochem. properties, d. functional theory calculations, hole-transporting properties, X-ray diffraction, hole transfer dynamics, hydrophobic properties, surface morphol., and photovoltaic performances were measured and discussed. Device performance depends on the methoxy group positions. GJ-pp shows the best power conversion efficiency (17.23%) among the three twin-carbazole-based HTMs, and slightly lower than that of the spiro-OMeTAD-based devices (17.96%). However, the GJ-pp-based devices show outstanding thermal stability compared with the spiro-OMeTAD-based ones. Laboratory synthetic cost of GJ-pp is merely 29.0% of the purchasable spiro-OMeTAD price, and the concentration of GJ-pp is lower than that of spiro-OMeTAD (50.0 vs. 72.3 mg mL-1). The results demonstrate that the twin-carbazole moiety can endow enhanced charge transport properties due to its potential intermol. interactions, and the conjugated core is unnecessary for promising HTMs. In the part of experimental materials, we found many familiar compounds, such as Bis(4-methoxyphenyl)amine(cas: 101-70-2Product Details of 101-70-2)
