Abstract
Optoelectric properties of a novel liquid crystal zinc tetraphenyltetrabenz oporphyrin (ZnTPTBP) is studied with the aid of surface photovoltaic spectr oscopy (SPS) and electric-field-induced SPS. The surface photovoltage respo nse at 550 nm under external field is assigned to the pi-pi* transmission i n the columns of micro pi system formed in ZnTPTBP solid film and is though t to be related with the electro-optical memory effect of liquid crystal po rphyrin.
