摘　　要：报道了一系列侧臂含有苯甲酸和苯甲酸脂的新型杯[4]芳烃衍生物与三价稀土(主要是Tb3+和Eu3+)形成配合物的光物理性质。配合物溶液的荧光光谱研究结果表明:骨架上的苯环和侧臂中的苯环均能将吸收的紫外光能量有效地传递给稀土离子,敏化发光效率与配体的空间位阻、配合物的稳定性有关。侧臂带有芳香羧酸基团的杯[4]芳烃衍生物,对稀土离子的敏化发光效果较好,是一类理想的具有天线效应的配体。The complexation luminescent behavior of calixarene derivative with lanthanoid ion (Tb\+\{3+\} or Eu\+\{3+\}) has been investigated. The results obtained indicated that calixarene derivative can form stable complex with terbium ion(III) in solution. Both phenol group and aromatic carboxylates can efficiently transfer the energy to the Tb\+\{3+\} or Eu\+\{3+\}. The energy transfer efficiency depends on the ligand structure and stability of the complexes.
