摘　　要：以咔唑为原料,合成了1种新型的咔唑类衍生物-9-异辛基-3,6-咔唑二丙烯酸,其结构经1H NMR、^13C NMR、IR和MS测试技术表征。利用UV、单光子液体荧光和固体荧光分析研究了中间体和目标产物在不同极性溶剂中的线性光学性质。结果表明,随着溶剂极性的增加,目标产物在300-500 nm范围内具有良好的紫外吸收和单光子荧光效应。以罗丹明B的乙醇液作为参比,计算目标产物的荧光量子产率均大于0.19。A new carbazole derivative, 9-isooctyl-3,6-carbazole dicrylic acid, was synthesized and characterized by ^1H NMR, ^13C NMR, IR and MS. UV, one-photon excited fluorescence spectra and solid fluorescence of the intermediate and title product in different polar solvents were investigated. The results show that the target product had good UV absorption characteristic and single-photon fluorescence effect at 300 - 500 nm with increasing polarity of the solvent. With the ethanol solution of Rhodamine B as a reference, we calculated the quantum yields of the target product in different solvents to be more than 0. 19. So the compound could be a potential luminescent material.
