Solid state photochromism of spiropyrans
International Journal of Photoenergy, 2005 A series of spiropyrans possessing photochromic properties in solid state were investigated. UV irradiation (λmax=365 nm) of the thin vacuum deposited spiropyran films results in conversion of the colorless form to the photocolored one.

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin
Angewandte Chemie, EarlyView.Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.
