Novel phosphonate and phosphonic acid raft agents and monomers, along with methods of their manufacture and use

Abstract

An intermediate compound for forming a RAFT agent is provided that can have the formula: where n is an integer from 1 to 20; m is an integer from 0 to 20; R1 is H, an alkyl group, or a cyano group; R2 is H, an alkyl group, or a cyano group; Y is OH, COOH, or NH2; and X is OH, COOH, NH2, a nitrobenzyl, benzyl, or para-methyl benzyl group. A RAFT agent is also provided that comprises a thiocarbonylthio-containing organic compound having a phosphonic end group. A method is also provided for forming a polymer chain on a surface of a nanoparticle utilizing the RAFT agent, along with nanoparticles and nanocomposites formed therefrom.
