OPTICAL AND ELECTROCHEMICAL PROPERTIES OF METALLOPHTHALOCYANINE DERIVATIVE LANGMUIR-BLODGETT-FILMS

The formation of high-quality Langmuir-Blodgett films of copper and ni ckel phthalocyanine derivatives substituted with short branched chains is reported. Ellipsometric and polarized optical absorption measureme nts suggest that the phthalocyanine molecules have a preferred orienta tion, with their large faces perpendicular to the dipping direction an d to the substrate plane. Electrochromic effects are also noted in the se multilayer films.
