Metal Coordination-Driven Photochromism in Schiff bases incorporating 1,2,4-triazole and hydroxyphenyl moieties

Solid-state photochromism is often suppressed in organic crystals by packing constraints. Herein, we report the coordination-driven activation of pronounced photochromism in a series of zinc(II) complexes with N-substituted 4-amino-1,2,4-triazole ligands....
