Sulfonated polyimides (SPIs) consisting of naphthalenediimide and sulfonated units alternately segmented by long aliphatic spacers have been facilely synthesized. Such an unprecedented molecular design of SPIs avoiding conventional aromatic-type imide units allows the stacking of naphthalenediimide moieties and aggregation of sulfonate groups simultaneously, imparting high conductivity and excellent hydrolytic stability.
