By condensation of squaric acid with 1a￣1g, a class of novel multiarm squaraines, namely 1,3 bis[4 N,N bis(2 hydroxyethyl)amino 2,6 dihydroxyl phenyl] squaraine(2a) and its analogs(2b￣2g) were obtained.

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;

Synthesis, Structure Chemistry of Polyoxometalate and Dye-polyoxometalate Supermolecules;

A number of organotin, cyclopentadienyltitanium, cyclopentadienylzirconium and organophosphoryl substituted polyoxometalates are reported in relation of their antitumor activity against SSMC-7721 and Hela human tumor cells.

Polyoxometalates (POMs) are a rich and diverse family of metal-oxygen clusters made up of early transitional metals with unique photonic, electronic, and magnetic properties and chemical reactivity that has promised dramatic applications in quite diverse disciplines, including catalysis, medicine, and materials sciences.
