| 摘 要： | 设计合成了12种含偶氮苯光学活性侧基的乙烯基单体,利用分光光度计测定测定了它们在乙醇溶液中的吸收峰的变化.结果表明,偶氮乙烯基单体的吸收波长受结构因素的影响很大,共轭体系与吸电子基的存在均会导致其波长向长波长方向移动. |
| 关 键 词： | 偶氮乙烯基单体 吸收波长 共轭体系 吸电子基 |

| Abstract: | The polymer of azobenzene side chain containing photochromism is a new type of material which store coptical information.The changes of absorbing wavelength of 12 kinds of azo-vinyl monomer copolymers synthesized according to documents were detected by spectrophotometer in alcohol.The results showed that the absorbing wavelength of azo-vinyl monomer were significantly affected by the molecular stucture of itself.The absorbing peak moved toward red shift because of the existence of conjugate system and electron withdrawing group. |
| Keywords: | azo-vinyl monomer absorbing wavelength conjugate system electron withdrawing group |
