Organic NLO Polymers. 2. Main-Chain and Guest-Host Chi(2)NLO Polymers: NLO-phore Structure Versus Poling

Abstract

Several new dipolar main-chain X (2) nonlinear optical (NLO) polymers were prepared in the study. The NLO-phores, based on alkoxy substituted alpha- cyanoacrylates, were also placed as monomeric guests within a poly(methyl methacrylate) host. Polar alignment of the NLO-phores by corona poling and their relaxation behavior was monitored by detecting the optical signal resulting from second harmonic generation. By making small variations in the structure of the NLO-phore, it was found that when hydrogen-bonding groups are rigidly coupled to the NLO-phore they are very effective for retaining polar asymmetry induced by poling and induced no deleterious effects on the alignment process. For main- chain NLOPs, it appears that for optimum alignment the bonding-axis and the polar-axis should not be parallel. NonLinear Optical, Corona Poling, Rigid-Rod Polymers
