Abstract
The second-order nonlinear optical coefficients d33 (-2ω: ω, ω) of polymer films doped with novel disazo dyes, which have a perfluoroalkylsulfonyl group as an electron acceptor and an extended π-electron system, are determined by second-harmonic generation (SHG) measurements at a wavelength of 1064 nm. Thin polycarbonate (PC) film doped with 4-(4-(4-perfluorobutylsulfonylphenylazo) naphthylazo)-N-ethyl-N-hydroxyethylaniline showed a large d33 value, 67 pm/V. 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 π-electron system.
