A synthetic route is described for the preparation of 1,4-di(1-pyrenyl)butadiyne. The target compound, after purification by extensive column chromatography, has been characterized by NMR and exact-mass spectrometry. This material is highly-fluorescent in solution and, relative to pyrene, strongly absorbing in the near-UV region. Phosphorescence is observed at 77 K and formation of the metastable triplet
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
