摘要: 合成了硫醚二酐和4-硝基-4'-[N,N-二(2-氨乙基)氨基]偶氮苯(二胺单体)及对应的硫醚聚酰胺酸,并对其结构进行表征.由于该发色团分子的一端有可以进一步聚合的氨基,它与硫醚酐所形成的聚酰胺酸在普通有机溶剂中具有良好的可溶性,NLO发色团和聚酰亚胺骨架的分解温度td分别为362℃和491℃,显现出了特殊的热稳定性.目前,这些聚合物在高敏感非线性光学材料方面显示着广泛的应用前景.

Abstract: Thioether dianhydride, 2,2'-{4-[(4-nitrophenyl)azo]imino}bis ethylamine(diamine monomer) were synthesized and characterized. Due to this chromophore molecule(diamine nonomer) have further polymerizable amino groups on one end of the molecule, the corresponding poly(amic acid) formed with thioether dianhydride exhibited a good solubility in common organic solvents. Decomposing temperature of the diamine chromophore in the poly(amic acid) and polyimide backbone are Td=362 ℃ and 491 ℃, respectively. These polymers are currently showing interesting potential in highly sensitive, nonlinear optical materials.

Key words: Thioether dianhydride, Electro-optic chromophore, Poly(am ic acid), Polyimide, Thermal stability
