Abstract

The second-order nonlinear optical coefficients d₃₃ (-2(omega) :(omega) ,(omega) ) of polymer films doped with novel disazo dyes, that have a perfluoroalkylsulfonyl group as an electron acceptor and an extended (pi) - electron system, are determined by second-harmonic generation (SHG) measurements at wavelengths of 900 - 1550 nm. Thin polycarbonate (PC) film doped with 4-(4-(4- perfluorobutylsulfonylphenylazo) naphthylazo)-N-ethyl-N-hydroxyethylaniline showed a large d₃₃ value, 67 pm/V, at a wavelength of 1064 nm. The decay of the d₃₃ value was slow due to the stability of the molecular arrangement in a polymer matrix at high temperature. The large d₃₃ values and the stability of polymer films doped with novel disazo dyes in this study are discussed in terms of electron acceptor substitution and an extended (pi) -electron system.
