摘要
合成一种新型配体3-(10-己基咔唑-3-基)丙烯酸(LCOOH),并通过红外光谱、元素分析、核磁共振、紫外可见光谱、单光子荧光、Z-扫描技术对其进行分析表征和性质研究,并解析其晶体结构.研究结果表明,该咔唑羧酸配体具有较好的聚集态发光性质,在DMF中有高的量子产率(Φ=10.5%),同时有良好的非线性光学特性和大的双光子吸收截面(σ=458.38GM),显示该类化合物在双光子非线性材料领域有潜在的应用前景.
In the thesis,a new ligand named 3-（10-hexyl-carbazole-3-yl）acrylic acid（LCOOH）has been synthesized and characterized by FT-IR,elemental analysis and 1 HNMR spectroscopy,UV-Vis spectroscopy,crystal structure,cyclic voltammetry（CV）analysis,single-photon fluorescence and Z-scan technique.The results show that the ligand presents excellent aggregative state luminescence,good quantum yield and a large twophoton absorption cross section,indicating that it has potential applications in two-photon nonlinear optical materials.
