测试了ω-对联苯基多亚甲基羧酸4-[5′-对联苯基-1,3,4-(口恶)二唑基-2′-]苄酯及其模型化合物2-对甲苯基-5-联苯基-1,3,4-,(口恶)二唑在不同极性溶剂中的荧光发射光谱。它们既能形成分子间的激基缔合物又能形成分子内的激基复合物和三分子激基复合物。实验结果表明,溶剂极性的增加,有利于分子内激基复合物和三分子激基复合物的形成。 The 2-para-biphenylylmethylene carboxylic acid 4- [5’-para-biphenyl-1,3,4-oxadiazol-2’- Fluorescence Emission Spectrum of Tolyl-5-biphenyl-1,3,4 - (oxadiazole) in Different Polar Solvents. They form both an exciplex and an exciplex and a triad excimer. The experimental results show that the increase of solvent polarity is conducive to the formation of intramolecular exciplexes and three-exciplexes.
