Photochromism of Diarylethene Molecules and Crystals: Memories, Switches, and Actuators

“…This section describes molecular design and control of the cyclization and cycloreversion quantum yields. Table summarizes photocyclization and cycloreversion quantum yields in n -hexane together with absorption maximum wavelengths and coefficients of typical diarylethenes. ,− …”

Design and synthesis of reversible solid-state photochromic pyrazolones by introducing a pyridine ring

“…S4, † and it can be seen obviously that they represent an approximate straight line, which shows that the photochromic reactions of 1 and 2 follow the first-order kinetics. 19 The slopes corresponding to the first-order rate constants of the two compounds are k e-k = 7.03 × 10 −4 s −1 for 1a and k e-k = 4.43 × 10 −4 s −1 for 2a, which indicates that the photoisomerization reaction of 1a is slightly faster than that of 2a.…”

A Highly Efficient Silole-Containing Dithienylethene with Excellent Thermal Stability and Fatigue Resistance: A Promising Candidate for Optical Memory Storage Materials

“…We believe that by utilizing this unique characteristic of siloles, the designed photochromic diarylethenes may readily give rise to some excellent photochromic properties as well as excellent thermal stability and fatigue resistance . To the best of our knowledge, although silole-containing materials have attracted growing interest and have been studied by many groups, use of the silole moiety as the heterocyclic backbone for photochromic dithienylethenes has not been reported . Herein, we report the syntheses of a silole-containing dithienylethene.…”
