Inprovement of the Condensing Agent on the Synthesis of Phenolphthalein;

Briefly on Colour Changing of Alcoholic Solution when Phenolphthalein Indicater Contacts with Anhydrous Sodium Alcoholate;

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.

Research and development of phthalocyanine compounds as organic photoconductive materials;

Conductivity of One-Dimensional Phthalocyanine Ligand;
