我们合成了含有光敏查耳酮部分的主链聚酰亚胺并研究了聚酰亚胺的热性能。聚酰亚胺由酸酐[4,4'-(六氟异亚丙基)二邻苯二甲酸酐(6FDA)或4,4'-联邻苯二甲酸酐(BPDA)]和含有查尔酮基团的二胺衍生物制备。带有6FDA衍生物的聚酰亚胺可溶于四氢呋喃、氯仿、N,N-二甲基甲酰胺等有机溶剂。另一方面，含有BPDA衍生物的聚酰亚胺不溶于普通有机溶剂。具有6FDA衍生物的聚酰亚胺不表现出任何中间相，而具有BPDA衍生物的聚酰亚胺表现出近晶相。
We synthesized main chain polyimides containing photosensitive chalcone moiety and investigated thermal properties of the polyimides. The polyimides were prepared by acid anhydrides [4,4′-(hexafluoro-isopropylidene) diphthalic anhydride (6FDA) or 4,4′-biphthalic anhydride (BPDA)] and diamine derivatives containing a chalcone group. The polyimides with 6FDA derivative were soluble in organic solvents such as tetrahydrofuran, chloroform and N,N-dimethylformamide. On the other hand, the polyimides with BPDA derivative were insoluble in common organic solvents. The polyimides with 6FDA derivative did not exhibit any mesophases, while the polyimides with BPDA derivative displayed a smectic phase.
