Surface potentials of phthalocyanine derivative Langmuir-Blodgett (LB) films on metal electrodes were studied. Two kinds of phthalocyanine derivatives (C6PcCu and CuttbPc) were examined as a function of the number of deposited layers. The distributions of spatial excess charge density and of electronic state at the metal/film interface were determined. It was found that these two distributions clearly depend on the two kinds of phthalocyanine derivatives.
