Polyphosphazenes

Abstract

The field of inorganic-organic macromolecules provides a common connecting point to the well-established areas of ceramics, metals, semiconductors, and classical organic polymers. In no system is this relationship clearer than in the field of polyphosphazenes, where controlled changes in macromolecular structure allow the formation of materials that are polymer, ceramics, or metal or semiconductors. Polyphosphazenes are long chain macromolecules that contain a backbone of alternating phosphorus and nitrogen atoms, with two organic, inorganic, or organometallic side groups attached to each phosphorus, as shown in structure. Because of the unusual methods of synthesis an almost infinite variety of side groups and combinations of different side groups can be linked to the backbone.
