摘要
为了改善CuI-pyridine配合物的物理性质,采用溶液搅拌法合成了CuI-pyridine配合物与β-CD的包合物,用IR、1HNMR、荧光光谱等分析方法对其进行了表征,并用电分析方法初步研究了各种气体对包合物修饰膜电极的响应。结果表明,CuI-pyridine-β-CD包合物为水溶性的荧光化合物(固体状态时EMmax=563 nm),荧光发射稳定;随着甲烷气体不断通入,包合物荧光强度逐渐降低,且甲烷气体对CuI-pyridine-β-CD包合物膜有显著的响应。
Inclusion complex of CuI-pyridine-β-CD was synthesized by solution mixing and characterized by IR、1H NMR and fluorescence,and the preliminary electrode response study between modified membrane and some gas have been done by the method of electrochemical analysis.The results showed that the physical properties of CuI-pyridine was improved.CuI-pyridine-β-CD are water-soluble,which could emit strong and stable fluorescence（EMmax=563 nm） in solid state,and its fluorescence could not disappear.The experiment revealed that with the add of CH4,the fluorescence intensity of inclusion decrease gradually.Moreover,there was significant response between CH4 and CuI-pyridine-β-CD modified membrane.
