Organic NonLinear Optical Polymers. 6. High Performance Materials Based on the Poly(p-phenylene) Backbone.

Abstract

This paper describes preliminary work exploring the feasibility of preparing high-performance NLO-materials based on the poly(p-phenylene) (PPP) backbone. Three new monomer/NLO-phores of the general formula: 4- RS02C6H4C(triple bonds)C(4-XC6H4) where R = 2,5-dichlorophenyl; 2a, X = H; 2b, X= OMe; 2c, X= NMe2 were synthesized and then homopolymerized using catalytic nickel and stoichiometric zinc to produce the poly(p-phenylenes), 3a-c, respectively, as low molecular weight materials (M sub n = 1800-6000). Both NLO- phores (2b-c ) dispersed in PMMA displayed good SHG signal stability at ambient temperature (approx. 12% loss/100 h). The oligomeric materials dispersed in PMMA showed a lower magnitude of X(2) or no NLO signal. Attempts to induce dipolar asymmetry in the homopolymers 3b and 3c by corona poling were unsuccessful.
