| 摘 要： | 文章发现被一取代二甲基硅芘和三甲基硅芘的最大吸收波长相等，而未取代的芘相比较红移10nm。二取代二甲基硅芘的紫外吸收波长比一取代二甲基硅芘最大吸收波长有红移10nm。荧光强度随硅烷基数的增多增强，而甲基数目对紫外和荧光性质没有大的影响。

| Abstract: | The UV absorption maxima of mono dimethylsilyl substituted pyrenes shifted to equal wavelength with mono trimethylsilyl substituted pyrene, but mono dimethylsilyl substituted pyrenes shifted to 10nm longer wavelength than that of unsubstituted pyrene. Absorption maxima of bis dimethylsilyl pyrenes also shifted to 10nm longer wavelength than that of mono dimethylsilyl substituted pyrene. Fluorescence intensities increased with the number of dimethylsilyl groups. The number of methyl groups don ＇t effect UV absorption and fluorescence properties of pyrene. |
