| 摘 要： | 本文对双荧光团化合物2-(ω-联苯基取代多亚甲基)-5-联苯基恶二唑—1、3、4,及其对应的模型化合物2-甲基-5-联基恶二唑,通过测定荧光光谱的方法,对分子内给体与受体之间的能量转移进行了研究,从实验结果初步得到了双荧光团化合物比相应的单荧光团化合物混合体系的能量转移速率高,荧光强度有明显的提高。并从化合物的结构上对给体与受体之间的距离对能量转移速率常数的影响作了初步探讨。

| Abstract: | Several bischromophore compounds 2-(ω-biphenylyl polymethylene)-5-biphenylyl oxadiazole-l,3,4(F1-(CH2)n-F2), compounds 1,2,3,4 respectively n = l,2,3,4, and the corresponding model compound 2-methyl-5-bi-phenylyl oxadiazole-1,3,4 (compound 5) have been synthesized. The intramc lecular energy transfer has been studied by fluorescence emission spectra. |
