ELECTRONIC PROCESSES IN PHTHALOCYANINE SOLIDS

The positive or negative photoconductivity effects are found between t he component of phthalocyanine dimixing composites and the photoconduc tivity by dimixing method. The relations between the crystalline forms and electronic structure of the composites and the photoconductivity are further studied through X-ray and XPS. The results indicate that t he composites may be a kind of new uniform eutectic composites, which can enhance or reduce the partial large transfer processes from phthal ocyanine rings to metals, and the processes are exactly correspondent with the positive or negative photoconductivity effects. A model of gr adually transferred charge in the phthalocyanine solids is put forward , which can better explain the electronic processes in the phthalocyan ine solids.
