【摘要】 由荧光或延迟荧光法研究了题示新的光敏离子载体与Ｌｉ＋ 、Ｎａ＋ 、Ｋ＋ 、Ｍｇ２ ＋ 、Ｂａ２ ＋ 和Ｐｂ２ ＋ 的主客体识别性质，测定了乙腈或水溶液中对应主－ 客配合物的稳定常数和识别敏感因子．由于香豆素上甲氧基的供电子性和羰基可能参与冠醚与金属离子的配位作用，稳定常数有了明显增大．更多还原

【Abstract】 The cation recognition properties of the title luminescent ionophore MMC-MAC(O 5 ) in acetonitrile or aqueous solution by the normal fluorescence or delayed fluorescence methods were studied and the corresponding stable constants of complexes and the recognition sensitive factors were determined by the modified H-B equation.The recognition mechanism between MMC-MAC(O 5 ) and metal ion was discussed based on the chemical construction of MMC-MAC(O 5 ) and the fluorescence enhancement effect of cation.更多还原
