Electrically conducting three-dimensional (octacyano phthalocyaninato polysiloxane) polymer

Polymeric (octacyano phthalocyaninato polysiloxane) has been prepared by reacting 1, 2, 4, 5 tetracyano benzene (TCNB) with silicon tetrachloride in refluxing quinolene and hydrolysing the resulting product with dilute alkali. The product has been characterized by infrared (i.r.), ultraviolet-visible (u.v.-vis.) spectra, elemental analysis and electron spectroscopy chemical analysis (ESCA). The polymer shows improvement in electrical conductivity by six to seven orders of magnitude (10-1 S cm-1) on thermal treatment. © 1989.
