| 摘 要： | 本文利用紫外-可见吸收光谱法、顺磁共振(ESR)法系统地研究了多甲川键菁染料光氧化反应机理,结果表明,单线态氧(1O2)、超氧阴离子(O2-·是导致染料光褪色的主要因素,而在没有氧气存在下,Dye-·也促使染料光褪色。

| Abstract: | In this paper, the photcoxidation mechanisms of polymethylene chain cyanine dyes were studied by U-V spectroscopy and Electron Spin Resonance (ESR). It was revealed that singlet oxygen (1O2)、 superoxide were the main factors causing the photofading of dyes ,and dye- would cause the photofading of dyes without oxygen. |

| Keywords: | polymethylene chain cyanine dye photooxidation singlet oxygen superoxide |
