Photochromism of diarylethene molecules and crystals
Proceedings of the Japan Academy, Series B, 2010 Photochromism is defined as a reversible transformation of a chemical species between two isomers upon photoirradiation. Although vast numbers of photochromic molecules have been so far reported, photochromic molecules which exhibit thermally irreversible photochromic reactivity are limited to a few examples.

Advanced Materials, Volume 38, Issue 4, 16 January 2026.A molecular motor with four‐state dynamic chirality is integrated into liquid crystals, enabling quadruple sequential helix inversions and high helical twisting power. Due to high motor efficiency, the supramolecular helicity can be controlled by near‐infrared light via upconversion nanoparticles, resulting in a robust, multistate, photoresponsive soft

Terrylene bisimide-diarylethene photochromic switch
Chemical Science, 2012 A new photochromic system 2o/2c based on a highly photostable terrylene bisimide (TBI) fluorophore and a diarylethene (DAE) photochrome has been synthesised and its photoswitching properties have been investigated by UV/vis absorption and fluorescence spectroscopy and by cyclic voltammetry.

A Scalable and Sustainable Synthesis of Indirubin Frameworks Enabled by Deep Eutectic Solvents
ChemSusChem, Volume 19, Issue 1, January 2026.A sustainable protocol for the synthesis of indirubin in a choline chloride/urea deep eutectic solvent at 70°C under air affords the product in 70% yield without chromatography. The method is robust, scalable to pilot scale, and enables late‐stage functionalization, granting access to a wide range of indirubin derivatives. CHEM21 green metrics validate

Optical differential reflectance spectroscopy for photochromic molecules on solid surfaces [PDF]
, 2018 Optical reflectance of thin adsorbates on solid surfaces is able to reveal fundamental changes of molecular properties compared to bulk systems. The detection of very small changes in the optical reflectance required several technical improvements in the
