Abstract: Provided are novel naphthalocyanine dimer compounds of the general formula:RO--YNc--O--NcY--OR (I)wherein Nc represents a naphthalocyanine moiety, which can be substituted or unsubstituted; Y represents a central hetero atom of the naphthalocyanine moiety; and, OR represents an alkoxide cap bonded to the central hetero atom Y, with the first carbon atom of the alkoxide (OR) capping group being a tertiary carbon. Also provided is a method for preparing the dimer compounds, which method comprises reacting a naphthalocyanine dihalide in solution with a tertiary alcohol and a nucleophile. The process efficiently and reproducibly provides a naphthalocyanine oxo-bridged dimer having terminal alkoxide caps.

Abstract: Provided is a method for preparing polysiloxy containing naphthalocyanine compounds. The method comprises reacting a cyclosiloxane with a nucleophile to open the ring of the cyclosiloxane. The ring opened cyclosiloxane is then reacted with a naphthalocyanine precursor and a capping group compound. The nucleophile can perform the dual role of the nucleophile and the capping group compound. The method permits the preparation of siloxane containing naphthalocyanine compounds in a more proficient manner through the use of cyclosiloxanes as reactants.

Abstract: Complex metal oxides are formed by calcining in molecular oxygen such as air at least one bimetallic complex of the formula A[BY] wherein A and B are metals and Y is a ligand associated with B. The bimetallic complexes are precipitated from aqueous solution by a transposition reaction of AX and M[BY] wherein X is a disassociable anion and M is a cationic species. The bimetallic complexes are useful in forming pure complex metal oxide fibers by a process of either dispersing the complex metal oxide or bimetallic precursors in a spinning composition of fluid organic polymer or by imbibing a polymeric fiber with species AX and precipitating out the bimetallic complex by treating the imbibed fiber with a compound containing the BY complex. The process is also useful in forming superconductive complex metal oxides.

Abstract: Boron-containing ceramics are formed from organoboron preceramic polymers which are carboralated acetylenic polymers. The polymers can be formed by carboralating acetylenic or diacetylenic diols and condensing the diols to form carboralated polyesters. In an alternative process, polydiacetylene formed by the polymerization of diacetylene monomers having conjugated triple bonds are carboralated subsequent to polymerization. A process for obtaining readily soluble polydiacetylenes comprises heating a diacetylene diol in a high boiling solvent.

Abstract: A process for producing boron-containing ceramics such as boron carbide and boron nitride comprises pyrolyzing a blend of a precarbonaceous polymer such as polyacrylonitrile and a boron-containing polymer such as that formed by the reaction of a borane with a Lewis base. Pyrolyzation in an inert atmosphere yields boron carbide while pyrolyzation in a reactive gas burns away the precarbonaceous polymer and yields a ceramic comprising the reaction product of boron and the pyrolyzation gas. Boron nitride ceramics are formed by pyrolyzing the preceramic blend in ammonia.
