Complexes in which fac-(bpy)Re(CO)3 is linked by a styrylpyridine to an amine or an azacrown ether show no photoreaction in acetonitrile in the absence of acid, but they photoisomerize readily at the stilbene-like bridging ligand when the terminal amine or azacrown ether group is protonated because an intramolecular energy-transfer mechanism becomes available.
