Diarylethene-Based Photoswitchable Inhibitors of Serine Proteases [PDF]
Angewandte Chemie - International Edition, 2021 Abstract A bicyclic peptide scaffold was chemically adapted to generate diarylethene‐based photoswitchable inhibitors of serine protease Bos taurus trypsin 1 (T1). Starting from a prototype molecule—sunflower trypsin inhibitor‐1 ( SFTI‐1 )—we obtained light‐controllable ...

Photochromic Diarylethene for Polarization Holographic Optical Recording
Materials Letters, 2007 Photochromic diarylethene, 1,2-bis[2-methyl-5-(3-fluorophenyl)-3-thienyl] perfluorocyleopentene (1a), was synthesized. The compound showed good photochromic reactions both in solution and in PMMA matrix by photo-irradiation.

Invisible photochromism of diarylethene derivatives
Chemical Communications, 2008Diarylethene derivatives with oxidized thiophene rings shift their absorption band to a shorter wavelength in the UV region upon photocyclization; no color change was observed during the photochromic reaction, and the invisible photochromism is advantageous for devices used under room light.

Photoconversion of a Protonated Diarylethene Derivative
The Journal of Physical Chemistry A, 2012A photochromic diarylethene with N,N-dimethyl substituted group 1a was prepared. 1a showed ring-opening and ring-closing photoisomerization with UV/vis light irradiation. Treatment of 1a with CF(3)COOH produced a protonated diarylethene 1aH. With UV light irradiation, 1aH photoconverted to protonated ring-closed isomer 1c, which is photoinactive. It is

Physical Sciences Reviews, 2020
AbstractThis article introduces the general characteristics of the diarylethene class of photochromic dye and the structural features that make photochromism possible. It touches on the methodologies employed to synthesize these compounds as well as the influences that typical substitution patterns exert on photocoloration.

Single Molecule Multiphotochromism with Diarylethenes
Accounts of Chemical Research, 2012In single photochromes, the two isomers that are interconverted in photoinduced reactions can serve as on and off states in a molecular switching device. The addition of several photochromic moieties onto a single molecule can allow the processing of more complex logical patterns.

A photochromic diarylethene with phenolic Schiff base 1a can be easily transformed to photochromic diarylethene with benzoxazole 3a in the conditions of base and phototrigger. Both of their photochromic properties are investigated. They show that the conversions of ring-open form to ring-closed form at photostationary equilibrium are ca.

The allomorphism of a photochromic diarylethene
Tetrahedron Letters, 2003Abstract The photochromic diarylethene, 1,2-bis(2-methyl-5-(2,2′-dicyanovinyl)-thien-3-yl)perfluorocyclopentene ( 1a ), was synthesized by a novel method. Two kinds of single crystals of the compound were obtained depending on the different recrystallization conditions and their structures were determined by X-ray crystallographic analysis ...
