Polymorphism of 1,2-bis(2-methyl-5-p-methoxyphenyl-3-thienyl)perfluorocyclopentene and photochromic reactivity of the single crystals

Four polymorphic crystals were obtained by recrystallization of 1,2-bis(2-methyl-5-p-methoxyphenyl-3-thienyl)perfluorocyclopentene (1a) from hexane. All crystals underwent photochromic reactions upon alternate irradiation with ultraviolet (λ = 370 nm) and

Optochemical control of transcription by the use of 7-deaza-adenosine-based diarylethenes

Out of nine different 7-deaza-adenosine diarylethenes, we identified a high-performance photoswitch, suitable for the synthesis of photochromic DNA. By using solid phase synthesis, a photoresponsive T7 promotor was generated which allowed reversibly modulating the rate of enzymatic RNA synthesisin vitro.

The mechanodonor-acceptor coupling (MDAC) approach for unidirectional multi-state fluorochromism

Uni-directional multi-state fluorochromic scaffolds are valuable photofunctional molecules and yet scarce. We report a general approach for their design, i.e., mechanodonor-acceptor coupling (MDAC). A photochromic molecule is a mechanodonor, due to its capability to convert photonic energy into mechanical force. Upon proper coupling, it can be used to drive a mechanochromic molecule for uni-directional multi-state fluorochromism. The embodiment of this approach is a rhodamine-dithienylethylene hydride (RDH), which has been successfully employed in super-resolution localization microscopy[Figure not available: see fulltext.]

Photochromism of new unsymmetrical diarylethenes with a quinoline moiety

Three unsymmetrical diarylethenes with a 6-membered quinoline moiety were synthesized to investigate the effects of the substituents on their photochromism, and fluorescence, and the structure of one diarylethene was determined by single crystal X-ray dif
