摘要
An ordered ladder polyester （LPE） was first synthesized through the ladder superstructure （LS） constructed by concerted interactions of hydroxyl- and aramide-based H-bonding and p-terphenyl （TP）-based π-stacking by dehydrochlorination condensation using phosgene （COCl2） as coupling agent. LPE was characterized by GPC, FTIR, NMR, XRD, DSC and AFM. Among them, a distinct image of regularly linear alignment corresponding to the ladder main chain of LPE was first revealed by high-resolution AFM.
