摘　　要：以4-氨基水杨酸、戊二醛、罗丹明酰肼为原料合成了一种新型的罗丹明酰肼衍生物L,采用红外、核磁和电喷雾质谱对其结构进行了表征。通过吸收光谱和荧光光谱,考察了其与不同金属离子的相互作用,结果表明化合物L对Cu^(2+)具有良好的选择性识别,可作为Cu^(2+)的光谱探针。L与Cu^(2+)结合比为1∶1,结合常数K=1.91×105 L/mol,检测限D=22.9nmol/L。The reaction of 4-aminosalicylic acid,glutaraldehyde and rhodamine hydrazide was prepared,being in a new rhodamine derivative L,which was characterized by IR,NMR and ESI-MS.The interactions between Land common cations were investigated by absorption spectra and fluorescence spectra.The results showed that the compound L has a good selective recognition for Cu^2＋,it can be used as a spectral probe for Cu^2＋.The binding ratio of Land Cu^2＋is 1∶1,binding constant K=1.91×105 L/mol,detection limit=22.9 nmol/L.
