A Dual Photochemically Active Molecule Showing Distributable Reactivity Based on Anion-Assisted Coordination Assembly.

Distributable reactivity of a dual photochemically active molecule functionalized by a carboxyl coordination unit has been achieved based on anion-assisted coordination assembly. The anions induce the photoactive ligand to align at different orientations in three-dimensional metal-organic frameworks, thus allowing the supramolecular systems to show photocycloaddition with simultaneous luminescence transformation or undergo photoinduced electron transfer accompanied by coloration-decoloration under alternating light and thermal stimuli.
