In a continuation of our studies on easily processable high-performance polymers [41-45], we report herein the synthesis of a series of novel aromatic polyamides containing both fluorene or xanthene cardo structures and fluorinated phenoxy pendant groups from two fluorinated isophthaloyl chlorides and four diamines containing cardo groups by the low-temperature solution polycondensation in N/N-dimethylacetamide (DMAc).
