N-Cycl[3,2,2]azine甲酰脲衍生物的合成及其荧光性质研究

Synthesis and Fluorescence Properties of the N-Cycl[3,2,2]azineacyl Urea Derivative

设计合成了N-Cycl[3,2,2]azine甲酰脲衍生物6,通过X-Ray对其进行了结构表征.研究了其在不同溶剂中的紫外光谱和荧光光谱,比较了它们的荧光量子效率.发现在乙腈中,其相对荧光量子产率达0.68.该化合物对溶剂极性也有一定的敏感性.上述研究结果为进一步选择其它客体,探索化合物6在分子识别中的应用建立了基础.

1,3-Dicyclohexyl-1-（3-phenyl-pyrrolo[2,1,5-cd]indolizine-1-carbonyl）-urea （6） was synthesized. Its structure was characterized by X-ray crystallography. The UV/Vis and fluorescence spectra of the compound 6 were measured and its fluorescence quantum yields were examined in different solvents. The studies indicated that the fluorescence quantum yield of the compound 6 is strongly solvent-dependent, its fluorescence quantum yield in MeCN is higher than in others （Φ=0.68, in MeCN）. These findings should facilitate the studies of other guest recognition by 6.
