| 摘 要： | 利用UV-Vis吸收光谱仪和光化学反应器研究了菁染料和份菁染料薄膜的光降解动力学.与相应的份菁染料相比,携带正电荷的菁染料薄膜具有相对较好的光稳定性.运用量子化学中的SCF-MO-PM3方法,全优化计算了这些染料的分子几何构型和电子结构,并解释了染料的光稳定性与其分子结构的关系.

| Abstract: | The photodegradation kinetics of cyanine dyes and merocyanine dyes in thin films has been studied by UV Vis absorption spectroscopy.Those cyanine dyes holding a positive charge in thin films have relative good photostability comparing with merocyanines in thin films.The relationship between photostability and chemical structure of dyes has been elucidated by SCF MO PM3 calculations. |
