Mechanistic Insight Into the Polymorph‐Dependent Photosalient Effect of a White Light or Two‐Photon Activated Photoreactive Molecular Salt

Angewandte Chemie, EarlyView.
Photocycloaddition in stilbene‐type salt polymorphs exhibit distinct light‐driven responses: OHT‐TI shows a violent photosalient effect under visible and NIR (two‐photon) irradiation, whereas OHT‐TII reacts statically. Packing and computational analysis reveals that shell‐like structures in OHT‐TI frustrate structural relaxation, accumulating explosive
