Copolymers of methyl methacrylate and chromophores with methacrylate end groups were obtained by radical polymerization. Their nonlinear optical properties ware examined by electric field induced second-harmonic generation (EFISH) measurements and compared with corresponding monomeric dyes. All of them had maximum absorption wavelengths between 480 and 510 nm. Values for μβ (dipole moment μ, molecular...
Polyesters with covalently bound azomethine and carbonanalogous dye moieties were obtained by polymer analogous reactions. Their nonlinear optical properties were examined by electric field induced second harmonic generation measurements and compared with corresponding monomeric dyes. All of them had maximum absorption wavelengths between 400 and 546 nm. Values forμβ (dipole moment μ, molecular hyperpolarizability...
