Synthesis of Perfluoroalkylsulfonyl-Containing Azo Dyes and Their Second-Order Nonlinearity

1.合成了全氟烷基磺酰基取代的苯类化合物。2.全氟烷基磺酰基取代的偶氮染料<33>在掺杂的PMMA中表现出比相应的硝基衍生物（DR 1）更高的二阶非线性系数（d_）和更好的弛豫行为，这可能归因于其更强的吸电子能力，全氟烷基磺酰基的长和刚性性质。3.与全氟烷基磺酰基连接的MMA共聚物-取代的偶氮染料比相应的硝基衍生物（DR 1）显示出增强的二阶非线性系数（d_<33>）和更好的弛豫行为。偶联组分中的N-烷基链越短，玻璃化转变温度（Tg）越高。全氟烷基磺酰基的链长不影响聚合物的Tg。

1.Perfluoroalkylsulfonyl-substituted benzenes have been synthesized.2.Perfluoroalkylsulfonyl-substituted azo dyes showed enhanced second-order nonlinear coefficients (d_<33>) and better relaxation behavior than the corresponding nitro derivative (DR 1) in doped PMMA.These can be attributed to stronger electron-withdrawing, long and rigid nature of the perfluoroalkylsulfonyl groups.3.MMA co-polymers attached with perfluoroalkylsulfonyl-substituted azo dyes showed enhanced second-order nonlinear coefficients (d_<33>) and better relaxation behavior than the corresponding nitro derivative (DR 1). The shorter the N-alkyl chain length in coupling component, the high the glass transient temperature (Tg). Chain length of pefluoroalkylsulfonyl group did not affect Tg of the polymers.
