A novel gated photochromic compound 1,8-naphthalimidepiperazine-tethered dithienylethene (Nap-Pip-DTE) was prepared to mimic a soft gear-shift based on alternative UV/Vis irradiation, protonation/deprotonation and copper(II) ion complexation/dissociation The fluorescence and absorption spectra were used as output signals. Copper(II) ion was introduced to mimic the parking (P) state by complexation with two intramol. piperazine moieties of Nap-Pip-DTE, transforming diarylethene moieties into the photoinactive parallel form.

Escribano, Alejandra published the artcileWhy Are Dithienylethene-Linked Biscobaltocenes so Hard to Photoswitch?, Computed Properties of 219537-97-0, the publication is ChemPhysChem (2017), 18(6), 596-609, database is CAplus and MEDLINE.

Attaching an organometallic unit to a dithienylethene (DTE) mol. switch can allow one to vary its switching and spectroscopic properties, and to create switchable magnetic properties. In this work, two different dithienylethene mol. switches are used as a bridge between two cobalt sandwich units. The only difference between the switching cores is in the size of the cycloalkene ring connecting both thiophene rings. The complexes present different oxidation states for the cobalt atoms, which are demonstrated to determine the switching reaction. The UV/Vis measurements show that while the Co(I) complexes undergo the switching reaction, the Co(II,III) complexes switch poorly. Kohn-Sham d. functional theory calculations indicate diabatic ring-closure mechanisms and a large number of excited states hindering the cyclization reaction and favoring the relaxation to the open form of the mol. switch.

Incorporation of the dithienylethene moiety as a substituent provides new ‘switchable’ phosphine ligands whose electronic properties are reversibly modulated by light. The presence of electron-withdrawing substituents in the photochromic unit increases the σ-donation gap between the photo-modulated open and closed phosphine isomers.

A series of novel dithienylethene-based colorimetric sensors 1a-1d with a typical donor-acceptor structure have been successfully developed, which exhibited solvent-dependent photochromic properties in solution, as well as high selectivity and sensitivity for the naked-eye detection of cyanide anion in 95% aqueous CH₃CN media. Moreover, it was found that different structures had a noteworthy effect on both their photochromic properties and colorimetric sensing for CN^–. The sensing mechanism based on the nucleophilic addition reaction with CN^– was confirmed by absorption spectral studies, ¹H NMR titration and DFT calculations Among them, the sensor 1b displayed highly sensitive to CN^– (35 s) and lower detection limit (0.25μM), which can be utilized as a potential colorimetric sensor for CN^– in our daily life and environment.

Yuan, Yucheng published the artcileReversible photo-switching of dual-color fluorescent Mn-doped CdS-ZnS quantum dots modulated by diarylethene molecules, Quality Control of 219537-97-0, the publication is Frontiers in Chemistry (Lausanne, Switzerland) (2019), 145pp., database is CAplus and MEDLINE.

A highly reversible dynamic hybrid system was established by mixing dual-color emitting Mn-doped CdS-ZnS quantum dots (QDs) with photo-switchable diarylethene mols. The diarylethene 1,2-bis(5-(3,5-bis(trifluoromethyl)phenyl)-2-methylthiophen-3-yl)cyclopent-1-ene I performed fabulous photo-switching property and high fatigue resistance in this hybrid system. The emission color switching between blue and pink of the system can be induced mainly by selective quenching/recovering of the Mn- photoluminescence (PL) of the QDs due to the switchable absorbance of the mol. I. Mechanistic studies showed that quenching of QD emission following UV illumination was caused by both Forster resonance energy transfer (FRET) and reabsorption by surrounding II mols. in the case of the Mn-PL and solely by reabsorption in the case of badngap-(BG-)PL. This photo-switchable system could be potentially used in applications ranging from self-erasing paper to super-resolution fluorescence imaging.

Cai, Xunzhi published the artcilePhotochromic dithienylethene-branched triptycene hybrids, Recommanded Product: 5-Chloro-3-[2-(5-chloro-2-methylthien-3-yl)cyclopent-1-en-1-yl]-2-methylthiophene, the publication is Dyes and Pigments (2015), 227-234, database is CAplus.

Dithienylethene and triptycene both have controllable structure and versatile performances. In this study, a series of triptycene hybrids decorated with different number of dithienylethene units have been developed for photochromic switch. The synthetic process is facile and efficient and all new compounds were clearly characterized by ¹H NMR, ¹³C NMR and HRMS. Their photochromism and spectroscopic properties have been investigated in dichloromethane and THF. The result revealed that the multi-dithienylethene units grafted to triptycene behaved independently and showed distinctive solvent-dependent photochromism in chloride solvents, which probably due to the introduction of controlled spatial arrangement of triptycene core. These distinctive characteristics might be potential used for high-d. multicomponent switches and detection of chloride solvents.

These organogelator mols. were found to be able to induce gelation in apolar solvents such as benzene, toluene and p-xylene to form entangled networks driven by intermol. hydrogen bonding together with π-π interactions. Their excellent reversible photochromism with thermal stability in both solution and gel states was observed, and the thermally reversible property in sol-gel transition was exhibited.

Cao, Xinhua published the artcileFluorescence and Morphology Modulation in a Photochromic Diarylethene Self-Assembly System, COA of Formula: C15H14Cl2S2, the publication is Langmuir (2011), 27(8), 5090-5097, database is CAplus and MEDLINE.

Switchable supramol. self-assemblies on the basis of interaction between melamine group containing photochromic diarylethene unit (DTE) and naphthalimide derivate (1) were designed and fabricated. 1 can gelate several aprotic solvents with different morphologies. The gel turned into partial gel in Et acetate with the addition of DTE as a guest mol. Both the absorption and fluorescence spectra of the assembly can be reversibly switched by alternating UV/visible light irradiation Meanwhile, the morphol. of the coassembly of 1₂·DTE changed to film from original pieces of gel 1 in Et acetate. When 1₂·DTE was irradiated by UV light, the film morphol. was converted into aggregated flakes. Moreover, the surface wettability of the complex can also be switched by light irradiation The photochromic diarylethene unit is able to modulate the fluorescence and morphol. of the assembled system only by virtue of light irradiation Therefore, these results provide further insights into fluorescence and morphol. controlling, especially application in upscale smart responsive materials.
