Optical Materials Express, 2016•opg.optica.orgWe report the design, synthesis and characterization of a series of electro-optic
chromophores comprised of amino-benzene with a benzyloxy group as the donor units,
thienyl-di-vinylene with ethylenedioxy as the π-conjugation bridge, and tricyanofuran
derivatives as the acceptor units. The improvement of linear and nonlinear optical properties
was found in electro-optic chromophores with ethylenedioxy compared with the
chromophores without ethylenedioxy. The data obtained from hyper-Rayleigh scattering …

The improvement of linear and nonlinear optical properties was found in electro-optic chromophores with ethylenedioxy compared with the chromophores without ethylenedioxy. The data obtained from hyper-Rayleigh scattering, absorption spectrum, and ^1H-NMR measurements indicate the improved structural stability of π-conjugation unit, which may be induced by the steric effect and partial intra-molecular hydrogen bonding related to ethylenedioxy.
