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.

Mechanically Triggered Chemical Recyclable Polyethylene‐Like Materials

Angewandte Chemie, EarlyView.
Polyethylene‐like copolymers with benchmark properties are prepared by embedding latent cyclobutene mechanophores to overcome PE's end‐of‐life limits. The mechanophores are inert in service but are selectively opened by solvent‐free ball milling to yield well‐defined telechelic oligomers.
