| 摘 要： | 本文报道了对苯二甲酸酯类生色团与苯所形成的激基复合物并讨论了这类激基复合物的溶剂效应.结果表明,在这类激基复合物体系中,激基复合物谱带中发射峰的位置明显地受溶剂酸性的影响,在缺质子溶剂中,荧光峰红移较小,随着溶剂酸性的增强,激基复合物谱带的红移增大.激基复合物谱带中发射峰的位置与溶剂特性常数S之间的关系符合Brownstein公式.

| Abstract: | The exciplex formation by terephthalate chromophores and benzene is reported.The solvent effect on the fluorescence spectra of the exciplex is examined and discussed.It is shown that the maximum of the exciplex fluorescence is dramatically affected by the acid strength of the solvent.In the aprotic solvent, the maximum of the exciplex fluorescence is located at a much lower frequency than in the protic solvent.The shift of the band maximum increases with increasing acid strength of the solvent.The relationship between the wavelength of the exciplex fluorescence band maximum and the characteristic parameter of the solvent obeys Brownstein equation satisfactorily. |
