Abstract

Re(I) complexes bearing thermally reversible photochromic naphthopyran axial ligands undergo highly efficient, reversible phosphorescence quenching actuated by either visible or UV irradiation. The photoinduced quenching of the triplet metal-to -ligand charge-transfer (3MLCT) emission is interpreted based on changes in the relative energies of the excited states.
