Side chain organiometallic polymers containing cyclopalladated potentially second order nolinear optical active fragments as pendants

摘要

Three new organometallic homopolymers and a copolymer have bee nobtained by radical polymerization of acrylic monomers. The monomers were obtained by birdge splitting reaction from cyclopalladated dinuclear species and the appropriate imines. The polymers exhibit good thermal and chemical stability and are soluble in common organic solvents. Their potential ability to display second order nonlinear optical activity was tested by solvatochromic effect measureemnts on the corresponding monomers. In particulr, the copolymer appears to be the most versatile in consideration of its thermla behaviour, solubility and inherent viscosity.
