  • Chemically synthesized graphene nanosheets offer device design flexibility and improved optoelectronic performance. Here, the authors report solution-processed distributed feedback lasers with graphene nanosheets as active media having linewidths < 0.13 nm, long operational lifetimes and low thresholds.

  • Synthetic oligo-/polyynes with unprecedented length are used to model the elusive carbon allotrope carbyne. Spectroscopic and physical analyses show that endgroups influence the properties of shorter derivatives, but these effects predictably diminish in longer molecules. Molecular symmetry documents the evolution of characteristics from oligoynes to polyynes and offers predictions for the D∞h structure of carbyne.
