The development of new methods for the production of complex materials is one of the most important problems in modern solid state chemistry and materials science. This project is attempting to apply the synthetic principles which have evolved in inorganic and organometallic chemistry to the production of important non-oxide ceramics, such as boron nitride, boron carbide and metal borides. Our recent work has now resulted in the production of several new polymer systems, including poly(vinylborazine), poly(vinylpentaborane) and poly(borazylene), that have proven to be high yield precursors to boron nitride and/or boron carbide. Current work is now directed toward the synthesis of new types of molecular and polymeric boron-containing species and an exploration of the solid state properties of the ceramics that have been produced in these studies.
