摘要：

The synthesis kind hyperpolarizabilities of a series of push-pull chromophores containing bis-(4-methoxyphenyl)-amine donor and efficient acceptors bridged with ring locked polyene are presented. The chromophores are readily soluble in common organic solvents and exhibit high thermal decomposition temperatures (highest T-d = 330 degrees C). Molecular hyperpolarizabili ties (beta) of the chromophores were measured by Hyper Rayleigh Scattering (HRS) at 1604 nm (highest beta = 20,000 x 10(-30) esu). These chromophores can be used to develop electro-optic (EO) materials due to their large optical nonlinearities, good absorption characteristics, high thermal decomposition temperatures, and excellent solubility with organic solvents and polymeric materials.
