| 摘 要： | 本文分别用亚甲基和甾体雌二醇刚性链将吲哚与9,10-二甲氧基蒽连接起来,合成了两个分子内能量转移体系,研究了分子內吲哚的激发能向9,10-二甲氧基蒽的传递过程与距离及溶剂环境的关系;发现在两个体系中激发吲哚都可以发生从吲哚到9,10-二甲氧基蒽的单重态-单重态能量转移,在远距离的条件下,能量转移按偶极子-偶极子共振机制进行,由实验结果,根据Forster公式计算得到的给体与受体之间的距离与用分子模型测量得到的距离是一样的,并研究了溶剂极性对能量转移过程的影响。 |

| Abstract: | Two energy donor-acceptor systems have been synthesized by linking indole and 9,10-dime-thoxyanthracene with methylene and β-estradiol spacers. Intramolecular energy transfer between indole and 9, 10-dimethoxyanthracene and its relation to distance and solvent polarity have been studied. Efficient singlet energy transfer can take place in two systems. When energy donor and acceptor are separated by long rigid β-estradiol the mechanism of energy transfer is dopole-dipole interaction. The distance between donor and acceptor calculated by Forster theory agrees with that obtained from Corey-Pauling-Koltun (CPK) model of molecule and the effect of solvent polarity on energy transfer has also been investigated. |
