Building a 22-ring nanographene by combining in-solution and on-surface syntheses

A nanographene formed by the fusion of 22 benzene rings has been prepared by combining an in-solution Pd-catalyzed cycloaddition reaction and on-surface Au-promoted cyclodehydrogenation. The structure and electronic properties of the resulting three-fold symmetric C 66 H 24 molecule have been charac...

Description
Summary:A nanographene formed by the fusion of 22 benzene rings has been prepared by combining an in-solution Pd-catalyzed cycloaddition reaction and on-surface Au-promoted cyclodehydrogenation. The structure and electronic properties of the resulting three-fold symmetric C 66 H 24 molecule have been characterized by scanning probe microscopy with atomic resolution and corroborated by theoretical modelling. A nanographene formed by the fusion of 22 benzene rings has been prepared by combining in-solution cycloaddition reactions and on-surface cyclodehydrogenations.
