Photochromic Diarylethene‐doped SU‐8 for Rewritable Optics and Integrated Photonic Switching

Advanced Optical Materials, Volume 14, Issue 13, 3 April 2026.
A CMOS‐compatible photochromic host–guest material platform is realized by incorporating diarylethene molecules into SU‐8 photoresist. Reversible photoisomerization enables light‐programmable optical absorption, allowing rewritable optical patterning and port‐selective attenuation in integrated waveguides.

Photoisomerization‐Induced Solubility Change in a Diarylethene Derivative: A Theoretical and Experimental Study

ChemPhotoChem, Volume 10, Issue 3, March 2026.
Photoisomerization‐induced solubility change, which has not previously been reported for P‐type photochromic molecules, is demonstrated for a diarylethene (DAE) derivative. The closed‐form is markedly less soluble than the open‐form, giving a 10‐fold solubility difference in n‐octane at room temperature. Thermodynamic analysis combining theoretical and

Photoisomerization in Cyclic Dipeptide Derivatives: Photoswitchable Supramolecular Hydrogels and the Discovery of Hemipiperazine Photoswitches

ChemPhotoChem, Volume 10, Issue 3, March 2026.
Photoswitchable cyclic dipeptides (CDPs) can be used to prepare hydrogels that reversibly dissipate upon irradiation, or to photomodulate the development of living organisms. We report here applications and perspectives for CDPs containing azobenzene photoswitches or newly discovered hemipiperazine photoswitches in smart materials and biological ...
