摘要：

The conductivity (dark and photo) and the short-circuit photocurrent in symmetrical thin-layer cells containing zinc octakis(beta-decoxyethyl)porphyrin (ZnODEP) were determined as functions of temperature with the ZnODEP in the solid, liquid crystal, and isotropic liquid states. ZnODEP, a discotic liquid crystal, organizes to form columns, which act as one-dimensional conductors, in the solid and Liquid crystal phases. The changes in conductivity and photocurrent are interpreted by changes in structure and disordering (melting) that affect the rate of charge transport and trapping in the ZnODEP layer.
