合成了具有不同π电子共轭键3个新的有机光学材料4-(吡啶-4-乙烯),4’-(N,N-二羟乙基氨基)二乙烯苯(a),N-((4-(N,N-二羟乙基氨基)-苯亚甲基)-4-(吡啶-4-乙烯)苯胺(b)和4-(吡啶-4-乙烯),4’-(N,N-二羟乙基氨基)偶氮苯(c),使用脉宽8ns波长532nm调Q倍频ns/ps Nd∶YAG脉冲激光系统测试了它们的非线性光学性能,研究了分子结构与非线性光学性能之间的关系。结果显示这些化合物具有大的三阶非线性光学系数,这可能来源于它们长的D-π-A共轭电子结构;以N N双键为共轭键的化合物的非线性光学性能优于以C N或C C双键为共轭键的化合物。
Three novel organic optical materials, such as 4- (pyridine-4-vinyl), 4’- (N, N-dihydroxyethylamino) divinylbenzene (a) (4- (N, N-dihydroxyethylamino) -benzylidene) -4- (pyridine-4-ethene) aniline (b) and 4- , N-bishydroxyethylamino) azobenzene (c) were synthesized and their nonlinear optical properties were tested using a 532 nm Q-switched ns / ps Nd:YAG pulsed laser system with a pulse duration of 8 ns, Linear optical properties.The results show that these compounds have large third-order nonlinear optical coefficients, which may be derived from their long D-π-A conjugate electronic structure; NN double bond as a conjugate bond Nonlinear optical properties are superior to those with a CN or CC double bond as a conjugate bond.
