Research Interests:

The major research focus in our labs is the synthesis, characterization, and applications of both cyclic and polymeric phosphazenes. These inorganic materials consist of rings or linear chains of alternating nitrogen and phosphorus atoms. Our work focuses on the family of phosphazenes in which there are two substituents attached to each phosphorous atoms by direct P-C bonds. We prepare both the parent cyclic and polymeric phosphazenes from condensation reactions of N-silylphosphoranimines, Me3SiNP(OPh)RR1.
