Photoinitiated Electron Wire Properties of a Face-to-Face Porphyrin Tetramer - Insertion in Ultrathin Membranes
Information processing on a molecular scale will hopefully be achieved by assemblies composed of molecules acting either as electronic components or as electron wires. A face to face porphyrin tetramer is designed here as a candidate for an electron wire. We present evidence from direct electric measurement for the electric conduction of such molecules embedded in an ultrathin membrane which spatially organize them. According to energetic considerations issued from electrochemical and spectroscopic data, an intramolecular charge shift following photoexcitation and photooxidation is more probable than transient formation of a biradical ion pair.
