Title: polydiacetylenes Long Title: IUPAC Gold Book - polydiacetylenes DOI: 10.1351/goldbook.08889 Status: current Definition 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.
