铜离子催化DPKA关环反应及其潜在应用（CuⅡ-induced Ring-formation Reaction of Di-pyridylketone Azine and Its Potential Application）
二吡啶酮肼合物 离子识别 荧光 铜离子
font style='font-size:12px;'>
2010/8/18
铜离子催化的氧化关环有机反应，用于选择性荧光探测金属铜离子的存在。晶体结构和光谱分析表明,在DPKA的乙腈/水混合溶剂中，引入铜离子可以促使苯并三氮唑类荧光化合物(2)的形成，该反应可以使得溶液的荧光明显增强。而且在滴定溶液里，引入Cu2+螯合剂EDTA，并不能使得溶液的荧光减弱，表明荧光是由有机物2发射的。同时，其他金属离子的引入并不能产生荧光，而且干扰离子的存在也不能使得荧光光谱发生显著改变，...
