报告内容:Low dimensional (D) carbon allotropes like graphene and nanotubes (CNTs) are extremely attractive because of their unique and outstanding properties in the focus of actual science & technology. In contrast much less is known for the last missing allotrope, infinitely long sp1 hybridized atomic strings, i.e. carbyne. This seems very surprising as the pioneering work of acetylenic polyynes of A. Baeyer dates back to 1885. But, because of the strong reactivity of carbyne so far only short polyyne chains below 100 atoms could be confirmed. My recent breakthrough of a bulk synthesis of confined carbyne inside double-walled CNTs with a record length of more than 6000 carbon atoms (Nat. Mater. 15, 634, 2016) opens a trail into uncharted territory, which will now allow for the first time unraveling its intrinsic properties.

石磊博士简介:Dr. Lei Shi obtained his PhD degree (in Physics) from the University of Vienna in 2015, and currently working at the same University as a postdoc. His current research interests focus on real 1D linear carbon chains and carbon nanotubes by using the state-of-art near/far field resonance Raman specrtroscopy. Dr. Shi is the author of >15 peer-reviewed papers in international journals, such as Nature Mater., Nano Res., Adv. Mater, and so on.
