一类新型非线性光学材料——二苯甲酮衍生物的合成及性能研究

STUDY ON THE SYNTHESIS AND PROPERTIES OF BENZOPHENONE DERIVAITVES A NEW KIND OF NONLINEAR OPTICAL MATERIALS

为寻求新型、高效、优质倍频材料,我们合成了一类新型二苯甲酮类化合物,并对其红外、紫外、光声光谱及倍频性能进行了系列研究,发现二苯甲酮类化合物具有较强的倍频效率和较短的截止吸收波长,有着广泛的应用前景。

Aiming to seek new kinds of second-order nonlinear optical materials with high efficiency and good quantility, we have designed and synthesised a new kind of benzophenone derivatives. Analyses of their IR, UV, pnotoacoustic spectrum and second harmonic generation(SHG) properties indicates that they have large nonlinear optical susceptibilities and short cut-off wavelengths, holding promise for wide applications.
