双偶氮吡啶的多种合成方法

The synthesis methods of pyridine bis-azo

1,4-二[2-(4-吡啶)乙烯基]-苯(简称BPEB)是一种暗红色固体。是一种典型芳香族共轭大π键的化合物及重要的有机发光材料。BPEB可应用于发光二极管(LED),发光电化学池(LEC),光伏打电池等器件.这类化合物不仅可以作为发光材料,还可以通过修饰得到具有分子或离子识别、信息存储性能的特殊功能材料。本文阐述了BPEB的几种合成方法,并对这些合成方法进行了分析比较,得出了合理的工艺路线及适宜的工艺条件。

1, 4-bis [2-（4-pyridyl） ethenyl]-benzene （BPEB） is a dark red solid. Molecular formula for C20 H16 N2. Dissolve in ethanol, ethyl ether, chloroform and other organic solvents. It is a typical aromatic conjugate with the a bond compounds,BPEB is an important organic light-emitting materials. It can be applied to light-emitting diode （LED）, luminous cell （LEC）, a battery, such as photovoltaic devices. Not only can these compounds as luminous materials, can also be modified with molecules or ions identification, information storage performance of the special functional materials. Synthesis methods of BPEB were explained, and analyse. Got a reasonable process and the appropriate conditions.
