New Thermally Irreversible and Fluorescent Photochromic Diarylethenes
The Journal of Physical Chemistry A, 2008A photokinetic investigation is here carried out on four newly synthesized diarylethenes with the aim to test their performance as photoreversible chromogenic and light emitting materials. The pentatomic ring, which fixes these diarylethenes in the cis conformation, contains a Si atom or a PO group.

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.

A Novel Unsymmetrical Photochromic Diarylethene
Key Engineering Materials, 2011A novel unsymmetrical diarylethene derivative bearing both phenyl and thiophene moieties, in which a chlorine group was substituted at the para-positions of the terminal phenyl ring, was synthesized. At the same time, its photochromic properties and fluorescence switch were investigated in detail.

Photochromism of Single Crystalline Diarylethenes
Chemistry Letters, 1995Abstract 1,2-Bis(2,4-dimethy-3-thienyl)perfluorocyclopentene was found to undergo a reversible photochromic reaction in a single crystalline phase with rotation of the thiophene rings. Both the open-ring colorless and the photogenerated red isomers were thermally stable even at 100 °C.

Fluorescent Photochromic Diarylethene Oligomers
2003Fluorescent photochromic materials collect strong interest for their capability of controlling fluorescence by photochromic conversion of materials. In particular fluorescent diarylethenes, which shows reversible change in fluorescence intensity with photochromic reaction, are useful for light probe and non-destructive optical readout system.1 Since ...

Hybrid Organic–Inorganic Photon-Powered Actuators Based on Aligned Diarylethene Nanocrystals
Chemistry of Materials, 2019When photochromic molecules are organized in a crystal, the small-scale forces generated by molecular photoisomerization events can combine together to generate work on micro- or macroscopic length scales.

Photochromic diarylethene molecules and crystals
Pure and Applied Chemistry, 2009Abstract Some of the diarylethene derivatives were found to undergo photoisomerization reactions between two isomers even in the single-crystalline phase. The two isomers have different electronic as well as geometrical structures. The electronic structure change induces the reversible color change of the crystal.

We report three self-assembled iron complexes that comprised an anti-parallel open form (o-Lanti ), a parallel open form (o-Lsyn ), and a closed form (c-L) of diarylethene conformers.

Photocyclization Dynamics of Diarylethene
2020The focus of this chapter is a study that uses UED to probe the atomic motions that take place during the ‘photocyclization’ or photoinduced ring-closing reaction of the molecule 1,2-bis(2,4-dimethyl-5-phenyl-3-thienyl)perfluorocyclopentene, herein abbreviated to PFC.
