摘要： 通过5，17-二氨基杯[4]芳烃衍生物与7-羟基-8-甲酰基-4-甲基香豆素缩合，得到了一种以亚胺基团为离子载体、香豆素为荧光基团的新型杯芳烃荧光识别试剂。 采用IR、1H NMR、13C NMR和MS测试技术表征了合成化合物的结构。 通过紫外光谱和荧光光谱，研究了其对过渡金属和重金属离子的识别性能。 结果表明，该化合物对Fe3+和Cr3+离子具有选择识别能力，与Fe3+和Cr3+配合的化学计量比为1∶1，配合生成常数分别为4.1×105和1.07×105 L/mol。

Abstract: A novel fluorescent calix[4]arene derivative(1) bonded with coumarin units as fluorophores and imino groups as ionophores was synthesized by condensation of 5,17-diaminocalix[4]arene with 7-hydroxy-4-methyl-2-oxo-2-H-chromene-8-carbaldehyde. The structure of compound 1 was fully characterized by IR, 1H NMR, 13C NMR and MS. The recognition properties of compound 1 toward transition and heavy metal ions were studied by UV-Vis and fluorescent spectroscopies. The results show that compound 1 can selectively recognize Fe3+ and Cr3+ ions. The complexation ratio of compound 1 with Fe3+or Cr3+ is 1∶1. The association constants of compound 1 with Fe3+ and Cr3+ were 4.1×105 and 1.07×105 L/mol, respectively.

Key words: aminocalixarene, coumarin-imino fluorescent reagent, synthesis, fluorescent recognition
