通过Suzuki反应,合成了两种新型的咔唑衍生物:9-己基-3,6-二(2-噻吩)咔唑 (1)和9-己基-3,6-二苯咔唑 (2),并利用1H NMR、 13C NMR、IR、MS和X-射线单晶衍射对它们的结构进行了表征.同时,利用紫外可见光谱、单光子荧光激发谱和理论计算对它们的光学性质进行了研究,结果表明:测量的单光子吸收性能和理论计算的结果比较符合;并进一步对它们的双光子吸收截面进行了理论预测:分别为177.51GM (1)和191.55 GM (2).“,”Two new carbazole derivatives, 9-(hex-1-yl)-3, 6-di (thien-2-yl) carbazole and 9-(hex-1-yl)-3, 6-di (phen-2-yl) carbazole were synthesized by Suzuki reaction. Their structures were characterized by 1H NMR, 13C NMR IR, MS and single crystal X-ray diffraction. UV and single-photon excited fluorescence of the two compounds were investigated by experiment. The calculated one-photon absorption properties were in good agreement with the experimental measurement, and the calculated two-photon absorption cross-sections of the two compounds by quantum chemical method were 177.51 GM for 1 and 191.55 GM for 2 respectively.
