摘要:

推荐了一个大学化学综合实验“9-(4-溴丁基)-9H-咔唑的相转移催化合成、表征及室温磷光性能研究”。实验利用相转移催化合成9-(4-溴丁基)-9H-咔唑分子,采用核磁共振、高分辨质谱和红外光谱对其分子结构进行表征,并利用紫外-可见吸收光谱、稳态/瞬态荧光光谱和密度泛函(DFT)理论计算对其室温磷光性能进行研究。本综合实验涵盖了有机化学、分析化学、物理化学、仪器分析以及理论化学的知识点,建议纳入化学专业高年级综合实验课程。

关键词: 咔唑, 相转移催化, 室温磷光, 化学综合实验

Abstract:

A new comprehensive university chemistry experiment, "Synthesis, structure characterization, and room temperature phosphorescence property of 9-(4-Bromobutyl)-9H-carbazole prepared by phase transfer catalysis method", was recommended for undergraduates. 9-(4-Bromobutyl)-9H-carbazole was synthesized by phase transfer catalysis reactions, and the structure and purity of 9-(4-Bromobutyl)-9H-carbazole were confirmed by nuclear magnetic resonance (1H NMR), high resolution mass spectrometer (HRMS), as well as fourier transform infrared spectroscopy (FTIR). The room temperature phosphorescence property of the 9-(4-Bromobutyl)-9H-carbazole was studied with UV-Vis absorption, steady and transient state fluorescence spectroscopy, and density functional theory (DFT) calculations. This comprehensive chemistry experiment included the knowledge of organic chemistry, physical chemistry, analytical chemistry, instrumental analysis and theoretical chemistry. Thus, the comprehensive chemistry experiment should be arranged for junior university students.

Key words: Carbazole, Phase transfer catalysis, Room temperature phosphorescence, Comprehensive chemistry experiment
