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
