Abstract

The present invention provides novel organic copolymers comprising alternating functional groups, wherein one functional group is phosphonate. In one embodiment, the copolymers comprise alternating phosphonate and N-substituted succinimide functional groups. In another embodiment, the copolymers are synthesized from maleimide and vinyl ether monomers, wherein the vinyl ether monomer possesses a pendant phosphonate functionality and the maleimide monomer is an N-substituted maleimide. Methods of synthesizing thin films with the novel organic copolymers, as well as chemical precipitation methods using the novel organic copolymers, are also provided.
