A novel multifunctional mol. BTE-CNPH was designed and synthesized by connecting 2-(3�5�bis(trifluoromethyl)-biphenyl-4-yl)-2-cyanovinyl group to both side of the bisthienylethene (BTE), which exhibited excellent aggregation-induced emission (AIE) and bistable photochromism. High-contrast (>60) reversible fluorescence switching was achieved in the 1D nanowires, solid of BTE-CNPH and also in a polymethyl methacrylate (PMMA) film loaded with 1% BTE-CNPH under the alternative irradiation by 365 nm and visible light. Interestingly, the nanowire-like assembly morphol. of BTE-CNPH in aqueous THF (THF) solution of specific concentration was observed to translate into amorphous pieces gradually upon prolonged irradiation by the 365 nm, accompanying with photo-tunable AIE emission.

Yao, Shengxin published the artcileSynthesis and spectroscopic properties of BODIPY-dithienylethene conjugates, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Journal of Porphyrins and Phthalocyanines (2021), 25(10/12), 930-936, database is CAplus.

Two red fluorescent triads containing photochromic dithienylethene moiety linked to two 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) via acetylene bond, 1a or single bond, 1b were synthesized and characterized. Although no evident absorption and NMR spectra changes were observed upon irradiation with visible light, the absorption and fluorescence spectra of 1a and 1b are remarkably solvent dependent, in contrast to those of the reference BODIPY-thienyl compounds 2a and 2b, which are essentially solvent independent. Fluorescence intensities of 1a and 1b decreased as the solvent polarity increased, and the fluorescence decay showed two exponentials in polar solvents other than n-hexane. DFT calculations have been carried out to elucidate the spectral behavior of investigated compounds

Cui, Shuzhen published the artcileSynthesis and characterisation of photochromic dithienylcyclopentene liquid crystal with thermal irreversibility, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Liquid Crystals (2016), 43(6), 803-810, database is CAplus.

A series of photochromic liquid crystal dithienylcyclopentene derivatives I (n = 4, 5, 6, 7) was synthesized from the initial material 2-chloro-5-methylthiophene. They were characterized by ¹H NMR, high resolution mass spectrometer, differential scanning calorimetry (DSC) and polarized optical microscopy (POM) with a hot stage. All of them exhibited excellent photochem. reversible isomerization between the open-ring form and the closed-ring form in both organic solvents and LC media, resulting in the color change between colorless and purple under different light irradiations. The typical textures from POM showed that their isomers both had nematic phase and smectic phase with different colors. These compounds with bent shape were more sensitive to light than those of diarylethenes reported.

These compounds could be used as two-photon switches and for the potential applications in three-dimensional optical storage.

Remy, Sandrine published the artcileFunctionalization of zinc oxide nanorods with diarylethene-based photochromic compounds, Quality Control of 219537-97-0, the publication is Dyes and Pigments (2011), 89(3), 266-270, database is CAplus.

Two diarylethene mols. functionalized with a carboxylic acid function were grafted onto the surface of zinc oxide nanorods. Photochromic studies based on electronic absorption spectroscopy in solution showed that the switching units operate in a bidirectional mode, allowing both ring closure and ring-opening processes to take place successively in photochem. sequences combining irradiations of the open species at 300 nm and the closed ones at 500 nm. Depending on the mol. structure, some losses were observed presumably due to photodegradation Compound 2 containing a terminal Ph unit provides a longer conjugation pathway, thus offering red-shifted electronic absorption and better photochem. stability.

Herder, Martin published the artcileImproving the Fatigue Resistance of Diarylethene Switches, Application In Synthesis of 219537-97-0, the publication is Journal of the American Chemical Society (2015), 137(7), 2738-2747, database is CAplus and MEDLINE.

When applying photochromic switches as functional units in light-responsive materials or devices, an often disregarded yet crucial property is their resistance to fatigue during photoisomerization. In the large family of diarylethene photoswitches, formation of an annulated isomer as a byproduct of the photochromic reaction turns out to prevent the desired high reversibility for many different derivatives To overcome this general problem, we have synthesized and thoroughly investigated the fatigue behavior of a series of diarylethenes, varying the nature of the hetaryl moieties, the bridging units, and the substituents. By anal. of photokinetic data, a quantification of the tendency for byproduct formation in terms of quantum yields could be achieved, and a strong dependency on the electronic properties of the substituents was observed In particular, substitution with 3,5-bis(trifluoromethyl)phenyl or 3,5-bis(pentafluorosulfanyl)phenyl groups strongly suppresses the byproduct formation and opens up a general strategy to construct highly fatigue-resistant diarylethene photochromic systems with a large structural flexibility.

A bis(pyrazolylpyridyl) ligand, L, containing a central photochromic dithienylethene spacer predictably forms a ferrous [Fe₂L₃]⁴⁺ helicate exhibiting spin crossover (SCO). In solution, the compound [Fe₂L₃](ClO₄)₄ (1) preserves the magnetic properties and is fluorescent. The structure of 1 is photo-switchable following the reversible ring closure/opening of the central dithienylethene via irradiation with UV/visible light. This photoisomerization switches on and off some emission bands of 1 and provides a means of externally manipulating the magnetic properties of the assembly.

We report the selective targeting of telomeric G4 DNA with a dithienylethene ligand and demonstrate the robust visible-light mediated switching of the G4 ligand binding mode and G-tetrad structure in physiol.-relevant conditions.

The photoswitching of photochromic bisthienylethene mixed electron donor-π-accepter (2D-π-A) type fluorescent dye with appropriate doping ratio was constructed, which showed excellent fluorescence switch “on” and “off” when the photochromic bisthienylethene undergoes ring-opening and ring-closed photoisomerization with UV and visible-light irradiation in solution and PMMA film. The erasable and rewritable photoimages on the photochromic bisthienylethene mixed 2D-π-A type fluorescent dye in PMMA were successfully demonstrated, which will provide a simple and viable method for optical data storage based photochromic fluorescent materials. These developments are crucial for fundamental research and eventual tech. application for all-photo mode high-d. optical data storage.
