The weight loss results showed that the adsorption of these compounds obeyed to Langmuir isotherm;the potentio-dynamic curves indicated both anodic and cathodic processes of mild steel corrosion in H_2SO_4 were suppressed by phthalocyanines,the Nyquist diagram expressed as a capacity.

The applications of the phthalocyanines in photodynamics therapy, light bleacher, catalysts, disc, nonliner optical proper-ity, electroluminace, gas sensor, electrochromic was reported in detail.

The paper discusses the molecular design of organic photoconductive materials based on the molecular structures of organic photoconductive materials, electronic distribution and the relationship between the charge transfer and photoconductivity, which is proved by the synthesis and photoconductivity study qf phthalocyanine polymers.
