We newly designd and synthesized EO chromophores with tricyanopyrroline (TCP) derivatives as the acceptor units, polyene as the π-electron bridges, and amino-benzene an alkyloxy group as the donor unit. Hyper-Rayleigh scattering (HRS), optical absorption, and ¹H-NMR spectrum measurements were performed for the EO chromophores to investigate linear and nonlinear optical properties.
