• 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 ( 3 MLCT) emission is interpreted based on changes in the relative energies of the excited states. UV or visible light induced cycling of the photochromic pyridylnaphthopyran ligand induces reversible switching of the Re( i )-centred phosphorescence.
