polydiacetylenes

https://doi.org/10.1351/goldbook.08889
Polymer prepared from buta-1,3-diyne (diacetylene) or a substituted buta-1,3-diyne or both in admixture (source-based polymer class name).
Notes:
  1. General formula of a regular polydiacetylene that is prepared by the photo-induced topochemical polymerization of a crystalline 1,3-diyne is as follows:
    where \(\ce{R^{1}}\) and \(\ce{R^{2}}\) are each hydrogen or an alkyl, aryl or heteroaryl group.
  2. Polydiacetylenes are a subclass of conjugated polymers and of polyacetylenes.
