We investigated the nonlinear optical (NLO) properties of two newly synthesized conjugated polymers P1 and P2 carrying 1,3,4-oxadiazole, 3,4-dibenzyloxythiophene, and 3,4-dialkoxythiophene moieties along the main chain, as potential NLO active materials. Their structures have been well characterized. The nonlinear measurements were performed by Z-scan using 532 nm, 7 ns laser pulses. Calculated values of figure of merit and β follow the criteria for good NLO materials. These results suggest that polymers are promising materials for applications in photonics.
我们研究了两种新合成的共轭聚合物 P1 和 P2 的非线性光学(NLO)特性,这两种聚合物的主链上分别含有 1,3,4-噁二唑、3,4-二苄氧基噻吩和 3,4-二烷氧基噻吩,是潜在的 NLO 活性材料。它们的结构已经得到了很好的表征。非线性测量是通过 532 nm、7 ns 激光脉冲的 Z 扫描进行的。计算得出的优点系数和 β 值符合良好 NLO 材料的标准。这些结果表明,聚合物是很有希望应用于光子学的材料。
