Electron paramagnetic resonance spectroscopy has been applied to obtain information on the in-plane anisotropy of Cu(II) [tetrakis-(3,3-dimethyl-1-butoxy carbonyl)] phthalocyanine (CuPcBC) molecules deposited as a Langmuir-Blodgett film on a biaxially oriented mylar substrate. We have found that the in-plane distribution of orientations of the film molecules depends on the angle between the asis of preferential order identified in the substrate and the dipping direction. The in-plane orientational anisotropy of the material in the film is mainly due to the ability of the substrate to induce oriented growth of CuPcBC molecules which reflects its surface order.

Abstract

Electron paramagnetic resonance spectroscopy has been applied to obtain information on the in-plane anisotropy of Cu(II) [tetrakis-(3,3-dimethyl-1-butoxy carbonyl)] phthalocyanine (CuPcBC) molecules deposited as a Langmuir-Blodgett film on a biaxially oriented mylar substrate. We have found that the in-plane distribution of orientations of the film molecules depends on the angle between the asis of preferential order identified in the substrate and the dipping direction. The in-plane orientational anisotropy of the material in the film is mainly due to the ability of the substrate to induce oriented growth of CuPcBC molecules which reflects its surface order.
