Abstract

Composite films of a meso-(tetramethylpyridinium)porphyrin (TMPyP) hybrid incorporated in mesoporous silica (MPS) and cast on a methyl viologen (MV ²⁺)/titania nanosheet hybrid were synthesized and a light-induced charge separation between the two could be observed. These composite thin films were able to initiate a one-electron reduction of the MV²⁺ ions accompanied by the simultaneous decomposition of the TMPyP organic dye within the mesoporous silica channels.
