Abstract (in Japanese) (See Japanese page) 
(in English) Recently, considerable attention has been paid to the development of polymeric electro-optic (EO) materials due to their potential applications in ultra-high-speed optical modulators and switches, digital signal processing, and optical sensors. One important theme in preparing highly effective EO materials is the development of EO chromophores with large molecular first hyperpolarizability and excellent thermal and chemical stability. In this paper, we report molecular first hyperpolarizability of a series of newly designed and synthesized EO chromophores that have amino-benzene with an additional alkyloxy group as the donor units, polyene, phenyl-di-vinylene, or thienyl-di-vinylene bridges as the π-electron bridges, and tricyanofuran derivatives as the acceptor units. We found an improvement in linear and nonlinear optical properties for the long π-conjugated EO chromophores having an amino-benzene donor with alkyloxy groups, compared with the benchmark EO chromophores without alkyloxy groups. We discuss a possible mechanism with a contribution for the improvement – intra-molecular hydrogen bonding.
