| 摘 要： | 在对不同取代的苯甲酰基硫代苯甲酸-S-苯酯的光物理性质进行研究时,发现其苯甲酰基在邻位时可观测到双磷光现象,本工作对这种现象的机理进行了研究,确定这种现象是由于溶剂的作用,使溶液中具有多种不同的构象体,不同异构体的磷光发射不同,其激发波长也不同,改变激发波长可观察到双重磷光现象。

| Abstract: | The photophysical behavior of S-phenyl thiobenzoates with different substituents has been studied at 77 K and different results were observed. It was found that the only 2-benzoyl derivative can emit dual phosphorescence. This phenomenon was caused by solvent effect. There are at least two conformational isomers existed in polar solution for 2-benzoyl derivative. The peak wavelength in phosphorescence spectrum depends evidently on the excited wavelength used. |

| Keywords: | benzoyl S-phenyl thiobenzoate dual phosphorescence conformational isomer solvent effect |
