The present invention provides a novel polyimide containing a diamine component that has a fluorene skeleton having a sulfonic acid group or a derivative thereof, and a novel polyimide-based polymer electrolyte membrane containing this polyimide as a main component and having properties based on this polyimide (for example, a good balance between the resistance to methanol crossover and the proton conductivity). The polyimide of the present invention contains a structural unit (P) represented by the following formula (1). The polymer electrolyte membrane of the present invention contains this polyimide as a main component.
本发明提供了一种新型聚酰亚胺,该聚酰亚胺含有一种二胺成分,该二胺成分的芴骨架具有磺酸基团或其衍生物,本发明还提供了一种新型聚酰亚胺基聚合物电解质膜,该膜以这种聚酰亚胺为主要成分,并具有基于这种聚酰亚胺的特性(例如,在抗甲醇交叉和质子传导性之间取得良好平衡)。本发明的聚酰亚胺含有由下式(1)表示的结构单元(P)。本发明的聚合物电解质膜以这种聚酰亚胺为主要成分。
