Research Interests

• Inorganic
• Polymers
• Synthesis

Our lab focuses on the synthesis, characterization and applications of both cyclic and polymeric phosphazenes, particularly those in which there are two substituents attached to each phosphorus atoms by direct P–C bonds, e.g., [(Ph)(Me)PN]_n. We prepare both the cyclic and polymeric phosphazenes with simple alkyl and aryl substituents, R and R', from condensation reactions of N-silylphosphoranimines, Me₃SiNP(OPh)RR', and subsequently study synthetic methods for modifying the alkyl and aryl groups attached to phosphorus to facilitate tuning the properties of these materials for potential applications in medicine and engineering.
