Synthesis of radiaannulene oligomers to model the elusive carbon allotrope 6,6,12-graphyne
Abstract
6,6,12-graphyne is an intriguing synthetic allotrope of carbon that is predicted to have unique electronic properties but has not been successfully synthesized. Here, the authors prepare a series of radiaannulene oligomers that can be regarded as large segments of this elusive graphyne allotrope.
