https://doi.org/10.1351/goldbook.08885

Definition:
Polymers composed of macromolecules containing exclusively alternating arenediyl or heterarenediyl (formerly arylene or heteroarylene, respectively) and ethynediyl (formerly ethynylene) constitutional repeating units in the backbone: [image] where Ar is a divalent arenediyl or heterarenediyl group (structure-based polymer class name).

Note: A polymer for which Ar is phenylene is a polyphenyleneethynylene.
