| 摘 要： | 以对硝基苯胺、苯胺、5 氨基嘧啶和N,N 二羟乙基苯胺为原料通过两步重氮化-偶合反应合成了两种给体-受体型非线性光学偶氮分子,用红外光谱、核磁共振、熔点、紫外光谱进行了表征,测定了分子的跃迁偶极矩,两个化合物的跃迁偶极矩分别为7 12D和8 76D,它们在不同极性溶剂中表现出明显的溶致变色效应,紫外吸收最大位移分别达到20nm和15nm。 |
| 关 键 词： | 非线性光学偶氮分子 重氮化-偶合反应 跃迁偶极矩 溶致变色效应 |

| Abstract: | Two novel nonlinear optical azo chromophores were designed and prepared from p-nitroaniline,aniline,5-aminopyrimidine and N,N-bis(hydroxyethyl) aniline by repeated diazotization-coupling reactions.The target compounds were characterized by NMR,IR,UV and melting point.The transition dipole moments of two compounds were determined,the measured value being 7.12 D and 8.76 D.The solvatochromic effect was discussed. |
| Keywords: | nonlinear optical azo chromophore diazotization-coupling reaction transition dipole moment solvatochromic effect |
