2-(2,4-二溴苯酚基)-1H-咪唑[4,5-f][1,10]邻菲啰啉及其亚铜化合物的合成与表征
摘 要本文用3,5-二溴水杨醛和5,6-二胺基-1,10-邻菲啰啉反应合成2-(2,4-二溴苯酚基)-1H-咪唑[4,5-f][1,10]邻菲啰啉（DIPP）配体。利用[Cu(CH3CN)4]ClO4、螯合双膦配体与DIPP反应，获得5种亚铜-双膦-DIPP配合物。通过紫外-可见电子吸收光谱（UV‒Vis）、荧光光谱和红外光谱（IR）等分析方法对配合物的部分光物理性能和结构进行了初步表征。结果显示，室温下该系列配合物发光性能良好。69121

Synthesis and Characterization of 2-(2,4-Dibromophenol)-1H-imidazole [4,5-f][1,10] Phenanthroline and Its Copper(I) Compounds
Abstract
2-(2,4-Dibromophenol)-1H-imidazole[4,5-f][1,10]phenanthroline (DIPP) was obtained by reaction of 3,5-dibromo-salicylaldehyde and 5,6-diamine-1,10-phenanthroline. Five cupprous complexes with diphosphine and DIPP ligands were acquired by reaction of [Cu(CH3CN)4]ClO4, DIPP and chelating diphosphine. Some photophysical properties and structures of the complexes are preliminarily characterized by ultraviolet visible (UV-Vis) electron absorption spectra, fluorescence spectra and infrared spectroscopy (IR) etc. The results show that these complexes exhibit good emission behavior at room temperature.
