Nonlinear Optical Properties of Composite Materials Based on Push-Pull Chromophores with Carbazole Donor and Quinoxalinone in π-Conjugated Bridge or in Macroacceptor

Poled thin films of composite polymer materials based on PMMA doped with high thermally stable chromophores with the structure D-π-A1-π-A2 and D-π-A1A2 with a carbazole donor D, a quinoxalinone core, A1, either in a π-conjugated bridge or in a macroacceptor, were obtained. The effect of the chromophore structure on the values and long-term stability of the nonlinear optical coefficient, d33, of such thin films has been shown.
