合成了3种具有双（氨基苯氧基苯基）砜结构的磺化二胺，即双[4-（4-氨基苯氧基）苯基]砜-3，3 ′-二磺酸（pBAPPS-3DS）、双[4-（4-氨基苯氧基）苯基]砜-2，2 ′-二磺酸（pBAPPS-2DS）和双[4-（4-氨基苯氧基）-2-（3-磺基苯甲酰基）苯基]砜（pBAPPS-2DSB）。以1，4，5，8-萘四甲酸二酐、磺化二胺和非磺化二胺为原料合成了一系列磺化聚酰亚胺（SPI），并与同系二胺或双[4-（3-氨基苯氧基）苯基]砜-3，3 ′-二磺酸（mBAPPS-3DS）的SPI进行了性能比较。这些SPI可溶于常见的非质子溶剂中，并且显示出相当高的质子传导率，除了基于pBAPPS-2DS的SPI之外，其传导率由于较低的水吸收而略低。这些SPI的水稳定性与磺化二胺的结构密切相关，其顺序为pBAPPS-2DSB> pBAPPS-2DS > pBAPPS-3DS> mBAPPS-3DS。它们的水稳定性远低于4，4 ′-双（4-氨基苯氧基）联苯-3，3 ′-二磺酸衍生物的SPI。从磺化二胺的碱性和磺化聚苯乙烯的溶解性两方面分析了其原因。© 2007 Wiley Periodicals，Inc.聚合物科学杂志A部分：聚合物化学45：2797-2811，2007
Three homologous sulfonated diamines bearing a bis(aminophenoxyphenyl)sulfone structure, namely, bis[4-(4-aminophenoxy)phenyl]sulfone-3,3′-disulfonic acid (pBAPPS-3DS), bis[4-(4-aminophenoxy)phenyl]sulfone-2,2′-disulfonic acid (pBAPPS-2DS), and bis[4-(4-aminophenoxy)-2-(3-sulfobenzoyl)phenyl]sulfone (pBAPPS-2DSB), were synthesized. A series of sulfonated polyimides (SPIs) were synthesized from 1,4,5,8-naphthalene tetracarboxylic dianhydride, these sulfonated diamines, and nonsulfonated diamines, and their properties were investigated in comparison with those reported for the SPIs from another homologous diamine or bis[4-(3-aminophenoxy)phenyl]sulfone-3,3′-disulfonic acid (mBAPPS-3DS). These SPIs were soluble in common aprotic solvents and showed reasonably high proton conductivity, except for pBAPPS-2DS-based SPIs, the conductivity of which was slightly lower because of the lower water uptake. The water stability of these SPIs considerably depended on the structure of the sulfonated diamines and was in the order of pBAPPS-2DSB ≈ pBAPPS-2DS > pBAPPS-3DS ≫ mBAPPS-3DS. Their water stability was much lower than that of the SPIs from 4,4′-bis(4-aminophenoxy)biphenyl-3,3′-disulfonic acid. The reason was discussed on the basis of the basicity of the sulfonated diamine and the solubility property of the SPIs. © 2007 Wiley Periodicals, Inc.
