摘要: Abstracts In this work, a series of novel second order nonlinear optical chromophores modified by heteroatom-groups in electron-donor has been synthesized and systematically investigated. The resulting exhibited both good thermal stability solubility common organic solvents. UV–Vis spectra density functional theory calculations were carried out to investigate the influence on electro-optic activities. results revealed that increasing strength will not always improve activity chromophore. There is best match for acceptor. As activities, doped polymer film- d3 displayed highest coefficient value 37 pm/v at doping concentration 25 wt%. These indicated activities could be enhanced finding acceptor chromophore design.
