Abstract
Abstract Two kinds of macrocyclic arylene ketone oligomers have been synthesized in high yield from phthaloyl dichloride and various bridge-linking electron-rich aromatic hydrocarbons via the modified Friedel–Crafts acylation reaction. The presence of a Lewis base in this reaction is demonstrated to be advantageous for forming macrocycle oligomers. These resultant oligomers can undergo melt ring-opening polymerization to give polymers with high Tg and excellent thermal stability.
