The synthesis and second harmonic coefficients, d33, and d3t as well as the related susceptibilities, :t~, of two new series of (NLO-dye methacrylate)-(methyl methacrylate) copolymers were investigated. The NLO-chromophores bound covalently to the polymer chain were 4-nitro-4'-dialkylamino-ct-cyano-
New NLO dye methacrylate-methylmethacrylate copolymers were synthesized. The NLO-chromophores bound covalently to the polymer chain are: 4-cyano-4'-dialkylamino-a-cyano-stilbene, 4-cyano-4'-alkoxy-:~-cyano-stilbene and 4-cyano-4'-alkoxy-stilbene. Films spincoated from these polymers were poled by a
This paper deals with relations between solvent diffusion and changes in second harmonic generation (SHG) in a side-group polymer with nonlinear optical (NLO) chromophores. The SHG signal of poled polymer thin films was measured as a function of time during the swelling process with methanol. The re
