Novel Properties of Supramolecular Complexes Formed by Pairing Cationic Porphyrin and Anionic Metal-Oxo Cluster

MTBPyP (me s o-tetrakis(4 -N- benzylpyridyl)porphyrin, M= H_2, Zn) be aring positive charge has been shown to associate with SiW_12O_40~(4-) in water solution. The spectral evolution and Job's plots analyses reveal that the relatively stable aggregates contain equal numbers of MTBPyP~(4+) and SiW_12O_40~(4-)
