Photochromic nitrospiropyrans substituted with 2,2'-bipyridine (bpy), [Ru(bpy)₃]²⁺, and [Os(bpy)₃]²⁺ groups were synthesized, and their photophysical, photochemical, and redox properties investigated. Substitution of the spiropyran with the metal complex moiety results in strongly decreased efficiency of the ring-opening process as a result of energy transfer from the excited spiropyran...
