4-Perfluoroalkylsulfonyl (RfSO2)-substituted azo nonlinear optical chromophores (NLOphores) showed enhanced second-order nonlinear coefficients (d33) and improved relaxation behavior compared with the corresponding nitro compound (Disperse Red 1 (DR 1)) in both doped poly(methylmethacrylate) (PMMA) and pendanted methylmethacrylate (MMA) copolymer.

The compounds act as second-order nonlinear optical chromophores. Compounds (Ib)-(Id) and the corresponding copolymers show enhanced second-order nonlinear coefficients and improved relaxation behavior compared with the nitro compound (Ia) and the corresponding copolymer. -(MATSUI, M.; KAWASE, R.; FUNABIKI, K.; MURAMATSU, H.; SHIBATA, K.; ISHIGURE, Y.; HIROTA, K.; HOSODA, M.; TAI, K.; Bull.
