Three 1,2-bis(2-alkyl-1-benzothiophene-3-yl)perhydrocyclopentenes with different alkyl chain lengths (Me, Et, and propyl) at the reactive carbons were synthesized, and their photophys. properties were compared with those of 1,2-bis(2-alkyl-1-benzothiophene-3-yl)perfluorocyclopentenes. The structures of the perhydrocyclopentenes were analyzed by X-ray crystallog., and their cyclization/cycloreversion reaction and fluorescence quantum yields, and fluorescence lifetimes were measured by steady-state spectroscopy and the time-correlated single photon counting method, resp. From these results, we found the following three differences between perhydrocyclopentenes and perfluorocyclopentenes. (1) For the closed-ring isomers, the absorption bands of the perhydrocyclopentenes (around 450 nm) shifted to a shorter wavelength than those of the perfluorocyclopentenes (around 530 nm) because of the acceptor nature of the perfluorocyclopentene moiety. (2) The cyclization/cycloreversion quantum yields of the perhydrocyclopentenes were slightly larger than those of the perfluorocyclopentenes in hexane. (3) Interestingly, the fluorescence of both the open- and closed-ring isomers was observed only for the perhydrocyclopentenes, and the lifetimes of the closed-ring isomers were estimated to be <30 ps.

Nonsymmetrical 3,4-Dithienylmaleimides by Cross-Coupling Reactions with Indium Organometallics: Synthesis and Photochemical Studies was written by Mosquera, Angeles;Fernandez, M. Isabel;Canle Lopez, Moises;Perez Sestelo, Jose;Sarandeses, Luis A.. And the article was included in Chemistry – A European Journal in 2014.Computed Properties of C9H7BrS This article mentions the following:

The synthesis and photochem. study of novel nonsym. 1,2-dithienylethenes (DTEs) with a maleimide bridge have been carried out. The synthetic approach to the DTEs was based on successive selective palladium-catalyzed cross-coupling reactions of 5-substituted-2-methyl-3-thiophenyl indium reagents with 3,4-dichloromaleimides. The required organoindium reagents were prepared from 2-methyl-3,5-dibromothiophene by a selective (C-5) coupling reaction with triorganoindium compounds (R₃In) and subsequent metal-halogen exchange. The coupling reactions usually gave good yields and have a high atom economy with substoichiometric amounts of R₃In. The results of photochem. studies show that these novel dithienylmaleimides undergo a photocyclization reaction upon irradiation in the UV region and a photocycloreversion after excitation in the visible region, thus they can be used as photochem. switches. ON-OFF operations can be repeated in successive cycles without appreciable loss of effectiveness in the process.

Reversible Photomodulation of Electronic Communication in a π-Conjugated Photoswitch-Fluorophore Molecular Dyad was written by Moreno, Javier;Schweighoefer, Felix;Wachtveitl, Josef;Hecht, Stefan. And the article was included in Chemistry – A European Journal in 2016.Quality Control of 3-Bromo-2-methylbenzo[b]thiophene This article mentions the following:

The extent of electronic coupling between a boron dipyrromethene (BODIPY) fluorophore and a diarylethene (DAE) photoswitch has been modulated in a covalently linked mol. dyad by irradiation with either UV or visible light. In the open isomer, both moieties can be regarded as individual chromophores, while in the closed form the lowest electronic (S₀→S₁) transition of the dyad is slightly shifted, enabling photomodulation of its fluorescence. Transient spectroscopy confirms that the dyad behaves dramatically different in the two switching states: while in the open isomer it resembles an undisturbed BODIPY fluorophore, in the closed isomer no fluorescence occurs and instead a red-shifted DAE behavior prevails. In the experiment, the researchers used many compounds, for example, 3-Bromo-2-methylbenzo[b]thiophene (cas: 10243-15-9Quality Control of 3-Bromo-2-methylbenzo[b]thiophene).

Photoinduced Refractive Index Change of a Photochromic Diarylethene Polymer was written by Kim, Eunkyoung;Choi, Yun-Ki;Lee, Myung-Hyun. And the article was included in Macromolecules in 1999.Recommanded Product: 10243-15-9 This article mentions the following:

The effect of photoirradiation on the refractive index of a diarylethene polymer was studied. The diarylethene polymer was prepared by a radical polymerization using 1-[6′-(methacryoyloxyethyloxycarbonyl)-2′-methylbenzo[b]thiophen-3′-yl]-2-(2”-methylbenzo[b]thiophen-3”-yl) hexafluorocyclopentene (BTF6MA), styrene, and Bu methacrylate. A colorless film prepared from the diarylethene polymer turned a deep red hue upon exposure to UV light. The red color was immediately bleached by visible light, and such coloration and bleaching of the polymer film could be switched reversibly by using two light source of UV and visible light. The refractive index (n_TE) of the polymer film, with 5.3 mol % of BTF6MA, was determined as 1.5555 and 1.5459 by a prism coupler using TE polarized light of 633 and 830 nm, resp. Upon irradiation with light of 365 nm, the refractive index was increased, resulting in a photoinduced refractive index change (Δn_TE) of 8 × 10^-4 as monitored by light of 830 nm. Δn_TE was dependent on the wavelength of the monitoring light. The dispersion of light in the diarylethene polymer film could be simulated by the Sellmeier equation, n_λ² = n_∞² + Dλ₀²/ (λ² – λ₀²), in which the refractive index at longest wavelength limit (n_∞) and the oscillator strength (D) for the colorless polymer film were determined as 1.5356 and 0.18, resp. Similarly, n_∞ and D values for the red polymer film, prepared by UV irradiation, were determined as 1.5368 and 0.042, resp.
