Summary

Descripción general del contenido del recurso.

The MLCT luminescence quenching of pyRe(CO)3bpy+ and/or the polymer {[(vpy)2-vpyRe(CO)3bpy] CF3SO3}n–200 by amines proceeds via an electron transfer reaction which produces amine radical cations and pyReI (CO)3(bpy)•/–ReI (CO)3(bpy)•, respectively. The quenching follows a typical Stern–Volmer kinetics for both pyRe(CO)3bpy+ and {[(vpy)2-vpyRe(CO)3bpy]CF3SO3}n–200. The observed rate constants for the quenching of the ReI -polymer luminescence by amines show “vestiges” of the inverted effect predicted by Marcus while the quenching of pyRe(CO)3bpy+ luminescence follow the Rehm–Weller type of behavior. The lower value obtained for the total reorganization energy of the ReI -polymer than that for pyRe(CO)3bpy+ is rationalized in terms of the retarded solvent motions inside the nanoaggregates formed by the ReI -polymer in acetonitrile solutions.
