Poly(arylene ether ketone)s composed of a 1,8-diaroylenenaphthalene moiety: a non-coplanarly accumulated aromatic-ring repeating unit

Poly(arylene ether ketone)s composed of a 1,8-diaroylenenaphthalene moiety, which is a non-coplanar accumulated aromatic-ring unit, were successfully synthesized through the nucleophilic aromatic substitution polycondensation of 1,8-bis(4-fluorobenzoyl)-2,7-dimethoxynaphthalene with several arene diols under mild conditions. The polymers show high glass transition temperatures ( T g ), poor solubility and good film-forming ability through heat casting.
