摘要：

A new, non-cross-linking route to increase the rigidity in poly(arylene ether)s has been developed, involving the conversion of a 2,2'-dibenzoylbiphenyl unit in the precursor polymer into a phenanthrene ring. Transformation proceeds intramolecularly under mild conditions without degradation. Thermal properties of the phenanthrene-based poly(arylene ether)s are significantly improved in comparison with their precursors.
