Cyclic and high polymeric phosphazenes can be modified by nucleophilic-type substitution reactions to generate a wide range of derivatives. Recent developments include the introduction of bioactive organic residues to yield biologically-active high polymers and the synthesis of transition metal derivatives of phosphazenes. In addition, hybrid phosphazene-carborane compounds have been prepared including examples in which nido-carboranyl units, attached to a phosphazene ring of chain, function as binding sites for transition metal organometallic units.
