Abstract:
Condensation polymer synthesis studies were initiated with an investigation of the dihydroxysilicon phthalocyanineresorcinol system. A crystalline polymer intermediate was isolated and is being characterized. The synthesis of difunctional carborane and neocarborane comonomers for use in similar condensation polymerization reactions was actively pursued. 6, 9-bisacetonitrilodecaborane was prepared and converted sequentially to 1, 2-bis acetoxymethylcarborane and 1, 2-bishydroxymethyl carborane. Carborane was also synthesized by the basic permanganate oxidation of the carborane diol. An investigation of the titanium phthalocyanine system resulted in the isolation and characterization of the novel 2 valence compound, PcTi. This compound is soluble and stable in sulfuric acid, forming a brown solution, but it can be oxidized in that medium to phthalimide by persulfate. Continued attempts to accelerate the formation of dichlorosilicon phthalocyanine were unsuccessful, but a highpressure facility for the improved preparation of this material has been installed. The product from the reaction of Dabco with chloraluminum phthalocyanine in dimethylformamide underwent hydrolysis to form hydroxyaluminum phthalocyanine hydrate. Author
