High glass transition chromophore functionalised poly(maleimide-styrene)s for second-order nonlinear optical applications
Nonlinear optical polymers with high glass transition temperatures were prepared by polymer analogous reaction of maleic anhydride copolymers, with aminoalkyl-functionalised azo- and stilbene chromophore a. Glas a transition temperatures from 178 to 228 degrees C were obtained. Poled films of the polymers were characterised by second-harmonic generation and showed a nonlinear optical response that is stable at elevated temperatures.
