Depending on the synthetic method, the heteroatom-doped hexagonal B nitride (h-BN) catalysts can have different configurational entropies possessing various at. short-range orderings or phase separations, leading to complex grain boundaries for catalytic reactions. Herein, several C and O co-doped h-BN (BCNO) catalysts with different at. orderings were synthesized from the ternary deep eutectic solvents (DES). The exptl. results indicated the low steric resistance DES induced high-entropy structures (HES) in the BCNO, which involved a high d. of grain boundaries. The HES was studied as a catalytic booster for the radical initiation of aerobic oxidative desulfurization (ODS) of diesel. As a result, the optimized BCNO catalyzed ODS process owned the shortest induction period, rendering the complete aerobic oxidation of refractory S compounds in 6 h.

The side-chain effects on the properties of the AEM were studied using the same membrane sample in different status. The variances between the different samples were eliminated. The hydroxide conductivity of AEM could be increased by reducing the distance between the cations.

A sym. diarylethene containing N-salicylideneaniline (Schiff base) units was synthesized. The structure was well confirmed by NMR spectroscopy, mass spectrometry, and elemental anal. Its photochromism was investigated by UV/visible absorption spectra and NMR. The result displayed that diarylethene can well perform photoisomerization, but no obvious intramol. proton transfer was observed Furthermore, we checked the effects of metal cations for the properties of N-salicylideneaniline-based diarylethene, which indicated that Cu²⁺ and Fe³⁺ cations can significantly affect the UV/visible absorption spectra of diarylethene ring-open and ring-closed isomers.

Lu, Tao published the artcileSynthesis and photochromism of dithienylethene-based isocyanide and gold (I) complexes with various alkyl chains, Quality Control of 219537-97-0, the publication is Dyes and Pigments (2021), 108964, database is CAplus.

The development of novel dithienylethene-based complexes is highly desirable for potential application in the photoresponsive optoelectronics. In this contribution, the authors designed and prepared four novel dithienylethene-containing isocyanides 9a–9d and their binuclear Au(I) complexes 3a–3d with various alkyl chains. They were fully characterized and confirmed by ¹H NMR, ¹³C NMR, ¹⁹F NMR, and HRMS (ESI-TOF). Upon alternating irradiation with UV light at 302 nm and visible light at 530 nm, these isocyanides and corresponding Au(I) complexes displayed good photochromic behavior. And the slight effect of the length of alkyl chains on photochromic properties of these isocyanides and Au(I) complexes was observed Also, compared to the precursors 9a–9d, their Au(I) complexes 3a–3d showed higher molar absorptivities for ring-open isomers, closing rate and cycloreversion quantum yields. Au(I) complexes displayed much more excellent fatigue resistance compared with that of isocyanides. Accordingly, these results further proved the formation of Au(I) complexes can promote photochromic behavior to some extent.

The two obtained polymers showed the reversible photochromic ability and excellent fatigue resistance. In the synthesis process of the two polymers, diarylethene and copolymer units were connected using rigid and flexible connections, resp., and thus diarylethene polymers with different spectral properties and mol. weights were obtained.

Zhang, Zhiwei published the artcileDiarylethenes with a Narrow Singlet-Triplet Energy Gap Sensitizer: a Simple Strategy for Efficient Visible-Light Photochromism, Name: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Advanced Optical Materials (2018), 6(6), n/a, database is CAplus.

All-organic visible-light photochromism is reported here via a novel strategy with narrow singlet-triplet energy gap (ΔE_ST) materials as a sensitizer. Taking advantage of the narrow ΔE_ST feature and the triplet-triplet energy transfer process, highly efficient photochromism of diarylethenes (DAEs) with both ring-open and ring-closure excitations shifted to visible light region is successfully achieved. Moreover, the wavelength of the visible excitation light can be easily modulated (e.g., from 405 to 470 nm) by elaborate selection of matched sensitized mols. The “write-and-erase” application of this photochromic system in polymer films is further demonstrated. This strategy provides a simple and versatile selection of well-matched DAE/sensitizer couples for visible-light photochromism without complicated mol. design.

Li, Yan-Kai published the artcileThe magic of integration: Exploring the construction of dithienylethene-based infinite coordination polymers and their synergistic effect for gaseous ammonia probe applications, Synthetic Route of 219537-97-0, the publication is Chinese Chemical Letters (2016), 27(4), 518-522, database is CAplus.

Infinite coordination polymers are recognized as excellent platform for functionalization. Dithienylethene motifs, which are one of the most attractive functional moieties, were incorporated into an infinite coordination polymer, to deliver a smart porous material that can response to external stimuli. The obtained dithienylethene-based infinite coordination polymers (named Cu-DTEDBA) share the advantages of both infinite coordination polymers (porosity and stability) and dithienylethene motifs (photochromism). The phys. and chem. properties of Cu-DTEDBA were characterized by FTIR, TEM, SEM, XRD, TGA, UV-visible, EDX and BET. Also, the combination of dithienylethene and infinite coordination polymers gives rise to a synergistic effect, which induces functional behaviors of ammonia sensor applications. Both open and closed forms of Cu-DTEDBA exhibit distinct colorimetric change upon exposure to gaseous ammonia, which is not observed in dithienylethene free mols.
