Type II porous liquids are demonstrated to be promise porous materials. However, the category of porous hosts is very limited. Here, a porous host metal-organic polyhedra (MOP-18) is reported to construct type II porous liquids MOP-18 is dissolved into 15-crown-5 as an individual cage (5 nm). Both the mol. dynamics simulations and exptl. gravimetric CO2 solubility test indicate that the inner cavity of MOP-18 in porous liquids is unoccupied by 15-crown-5 and is accessible to CO2. Thus, the prepared porous liquids show enhanced gas solubility Furthermore, the prepared porous liquid is encapsulated into graphene oxide (GO) nanoslits to form a GO-supported porous liquid membrane (GO-SPLM). Owing to the empty cavity of MOP-18 unit cages in porous liquids that reduces the gas diffusion barrier, GO-SPLM significantly enhances the permeability of gas.

The article was titled 《CO2 Chemisorption Behavior of Coordination-Derived Phenolate Sorbents》.HPLC of Formula: 33100-27-5 The article contains the following contents:

CO2 chemisorption via C-O bond formation is an efficient methodol. in carbon capture especially using phenolate-based ionic liquids (ILs) as the sorbents to afford carbonate products. However, most of the current IL systems involve alkylphosphonium cations, leading to side reactions via the ylide intermediate pathway. It is important to figure out the CO2 chemisorption behavior of phenolate-derived sorbents using inactive and easily accessible cation counterparts without active protons. Herein, phenolate-based systems were constructed via coordination between alkali metal cations with crown ethers to avoid the participation of active protons in CO2 chemisorption. Reaction pathway study revealed that CO2 uptake could be achieved by O-C bond formation to afford carbonate. CO2 uptake capacity and reaction enthalpy were significantly influenced by the coordination effect, alkali metal types, and alkyl groups on the benzene ring. In the part of experimental materials, we found many familiar compounds, such as 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5HPLC of Formula: 33100-27-5)

《Rationally Designed Polymer Conjugate for Tumor-Specific Amplification of Oxidative Stress and Boosting Antitumor Immunity》 was published in Nano Letters in 2020. These research results belong to Ma, Sheng; Song, Wantong; Xu, Yudi; Si, Xinghui; Lv, Shixian; Zhang, Yu; Tang, Zhaohui; Chen, Xuesi. Electric Literature of C10H20O5 The article mentions the following:

The crosstalk between tumor and stroma cells is a central scenario in the tumor microenvironment (TME). While the predominant effect of tumor cells on immune cells is establishing an immunosuppressive context, tumor cell death at certain conditions will boost antitumor immunity. Herein, we report a rationally designed tumor specific enhanced oxidative stress polymer conjugate (TSEOP) for boosting antitumor immunity. The TSEOP is prepared by Passerini reaction between cinnamaldehyde (CA), 4-formylbenzeneboronic acid pinacol ester, and 5-isocyanopent-1-yne, followed by azide-alkyne click reaction with poly(L-glutamic acid)-graft-poly(ethylene glycol) monomethyl ether (PLG-g-mPEG). Under tumor stimuli condition, CA and quinone methide (QM) are quickly generated, which cooperatively induce strong oxidative stress, immunogenic tumor cell death (ICD), and activation of antigen presenting cells. In vivo studies show that the TSEOP treatment boosts tumor-specific antitumor immunity and eradicates both murine colorectal and breast tumors. This study should be inspirational for designing polymers as immunotherapeutics in cancer therapy.

Dudko, Volodymyr; Ottermann, Katharina; Rosenfeldt, Sabine; Papastavrou, Georg; Breu, Josef published an article in 2021. The article was titled 《Osmotic delamination: Forceless alternative for production of nanosheets now in highly polar and aprotic solvents》, and you may find the article in Langmuir.Recommanded Product: 1,4,7,10,13-Pentaoxacyclopentadecane The information in the text is summarized as follows:

Repulsive osmotic delamination is thermodynamically allowed “”dissolution”” of two-dimensional (2D) materials and therefore represents an attractive alternative to liquid-phase exfoliation to obtain strictly monolayered nanosheets with an appreciable aspect ratio with quant. yield. However, osmotic delamination was so far restricted to aqueous media, severely limiting the range of accessible 2D materials. Alkali-metal intercalation compounds of MoS2 or graphite are excluded because they cannot tolerate even traces of water. We now succeeded in extending osmotic delamination to polar and aprotic organic solvents. Upon complexation of interlayer cations of synthetic hectorite clay by crown ethers, either 15-crown-5 or 18-crown-6, steric pressure is exerted, which helps in reaching the threshold separation required to trigger osmotic delamination based on translational entropy. This way, complete delamination in water-free solvents like aprotic ethylene and propylene carbonate, N-methylformamide, N-methylacetamide, and glycerol carbonate was achieved.

Panchenko, Pavel A.; Efremenko, Anastasija V.; Feofanov, Alexey V.; Ustimova, Mariya A.; Fedorov, Yuri V.; Fedorova, Olga A. published an article in 2021. The article was titled 《Ratiometric detection of mercury (II) ions in living cells using fluorescent probe based on Bis(styryl) dye and azadithia-15-crown-5 ether receptor》, and you may find the article in Sensors.Recommanded Product: 33100-27-5 The information in the text is summarized as follows:

Bis(styryl) dye 1 bearing N-phenylazadithia-15-crown-5 ether receptor has been evaluated as a ratiometric fluorescent chemosensor for mercury (II) ions in living cells. In aqueous solution, probe 1 selectively responds to the presence of Hg2+ via the changes in the emission intensity as well as in the emission band shape, which is a result of formation of the complex with 1:1 metal to ligand ratio (dissociation constant 0.56 ± 0.15 μM). The sensing mechanism is based on the interplay between the RET (resonance energy transfer) and ICT (intramol. charge transfer) interactions occurring upon the UV/Vis (380 or 405 nm) photoexcitation of both styryl chromophores in probe 1. Bio-imaging studies revealed that the yellow (500-600 nm) to red (600-730 nm) fluorescence intensity ratio decreased from 4.4 ± 0.2 to 1.43 ± 0.10 when cells were exposed to increasing concentration of mercury (II) ions enabling ratiometric quantification of intracellular Hg2+ concentration in the 37 nM-1 μM range.

In 2022,Hu, Zhitao; Cao, Xiaohui; Zhang, Xiaohui; Wu, Bin; Luo, Wenjun; Huang, Huahua; Li, Le; Chen, Yongming published an article in ACS Macro Letters. The title of the article was 《Catalytically Controlled Ring-Opening Polymerization of 2-Oxo-15-crown-5 for Degradable and Recyclable PEG-Like Polyesters》.Computed Properties of C10H20O5 The author mentioned the following in the article:

Poly(ethylene glycol) (PEG) has been extensively used in diverse applications. However, it is not biodegradable and shows abnormal immune responses. Herein, a fast, controlled, ring-opening polymerization (ROP) of 2-oxo-15-crown-5 (O-15C5) is reported to prepare well-defined PEG-like polyesters, poly(O-15C5). This approach relies on a coordination between the macrocyclic monomer and Na+ that increases the electrophilicity of the carbonyl group of O-15C5 and leads to a fast controlled ROP (dispersity, DM < 1.2). Both computational and mechanistic studies show that the selective Na+ binding to the monomer over poly(O-15C5) allows the ring-opening initiation and propagation to be more energetically favorable than side transesterifications. This is the key to control the challenging entropy-driven ROP of O-15C5. Moreover, with the aid of Na+ and organic base, poly(O-15C5) depolymerized readily into O-15C5 in 2 h. Also, it degraded in a buffer of pH 7.4 by hydrolysis. After reading the article, we found that the author used 1,4,7,10,13-Pentaoxacyclopentadecane(cas: 33100-27-5Computed Properties of C10H20O5)

The information in the text is summarized as follows:

A simple strategy for noncovalent immobilization of an olefin metathesis catalyst inside a (Cr)MIL-101-SO3Na metal-organic framework (MOF) was presented. The olefin metathesis active core-an alkylidene complex bearing an ammonium-tagged NHC ligand (Apeiron’s FixCat)-was immobilized by ion exchange facilitated using crown ether. The hybrid material thus obtained was shown with a number of model substrates to exhibit high activity and selectivity in a wide range of solvents. Next, selected polyfunctional pharmaceutically related substrates were transformed using 0.8-0.5 mol % of the Ru@MOF in polar solvents such as acetone and di-Me carbonate, making this technol. interesting in the context of green solvent use.

The Stokes-Einstein relationship relating the self-diffusion coefficient with the size of a diffusing particle (a hydrodynamic radius) breaks down in case of small mols. We present a novel method extending the range of validity of the Stokes-Einstein relationship by means of introducing a mol.-specific microfriction correction factor. This factor equals to 1 in the ordinary form of the Stokes-Einstein formula for ‘stick’ boundary conditions when mols. of solvent are much smaller than the diffusing particle. We have determined the microfriction correction factors for series of small mols.

The article conveys some information:

Proton exchange membranes with short-pathway through-plane orientated proton conductivity are highly desirable for use in proton exchange membrane fuel cells. Magnetic field is utilized to create oriented structure in proton exchange membranes. Previously, this has only been carried out by proton nonconductive metal oxide-based fillers. Here, under a strong magnetic field, a proton-conducting paramagnetic complex based on ferrocyanide-coordinated polymer and phosphotungstic acid is used to prepare composite membranes with highly conductive through-plane-aligned proton channels. Gratifyingly, this strategy simultaneously overcomes the high water-solubility of phosphotungstic acid in composite membranes, thereby preventing its leaching and the subsequent loss of membrane conductivity The ferrocyanide groups in the coordinated polymer, via redox cycle, can continuously consume free radicals, thus helping to improve the long-term in situ membrane durability. The composite membranes exhibit outstanding proton conductivity, fuel cell performance and durability, compared with other types of hydrocarbon membranes and industry standard Nafion 212.
