抄録

The large increase in molecular first hyperpolarizabilities (β) for the thienyl-vinylene bridge based nonlinear optical chromophores by modified acceptor and donor is reported. More than 3.5 times enhancement of βvalue is measured compared to the chromophone without the modification of acceptor and donor. This improvement is further proved by the intrinsic polarizations at zero frequency (β0) converted from β with a two-level model. Furthermore, molecular first hyperpolarizabilities in the molecular can be effectively translated into electro-optic coefficient. The chromophores show the onset docomposition temperatures is above 200°C, indicating that they possessing excellent thermal stability for the electro-optical applications.
