Synthesis of homopolymers bearing novel chromophore 4‐oxy‐4′‐(vinylbarbituratephenyl)azobenzene for nonlinear optical applications

The synthesis of new acrylate, methacrylate, and styrene with 4‐(oxyethoxy)‐4′‐vinylbarbituratephenyl azobenzene chromophore are described. The monomers were well characterized (NMR, UV, and IR) for the structure. These were then homopolymerized and characterized for spectral responses and thermal properties. The stronger acceptor barbiturate would result in more effective second harmonic generation. © 2000 John Wiley & Sons, Inc. J Polym Sci A: Polym Chem 38: 962–971, 2000
