Abstract

Photochromic materials are of interest because of their potential applications in optical information storage devices. Measurements on photochromic sodium nitroprusside (Na_2[Fe(CN)_5(NO)]) indicate that two metastable states are formed by irradiations of the crystalline solid: the first is an isonitrosyl (O-bonded NO); the second is an η^2-NO (side-on) complex. Phototriggered linkage isomerizations also occur in dimethylsulfoxide (dmso) complexes: notably, both photochemical Ru−S → Ru−O and thermal Ru−O → Ru−S reactions are observed in dmso solutions of [Ru(bpy)_2(dmso)_2]^(2+) (bpy = 2,2‘-bipyridine); and, as reported here, we find photochromism attributable to Ru−S → Ru−O rearrangement upon visible excitation of [Ru(tpy)(bpy)(dmso)]^(2+) (tpy = 2,2‘:6‘,2‘ ‘-terpyridine) in single crystals and films as well as in solution.
