Abstract: Transient surface photovoltage propertie of porphyrins and metalloporphyrins were studied. The photogenerated electronhole full separation time of porphyrin monomer was shorter than that of the dimer, and the photoge nerated electronhole full separation time of porphyrin monomer was shorter than those of metalloporphyrins. The transient surface photovoltaic signal of porphyrinCu is an especial one among those of metalloporphyrins. It had similarities to those of metal free porphyrins, and also similarities to those of metalloporphyrins. The different centralions had different influences on the separation rate of charge carriers.

Key words: porphyrin, metalloporphyrin, transient surface photovo ltage property
