TL;DR: In this paper, azomethine ylide homocoupling is used to insert an antiaromatic pyrazine ring into the core of a nanographene, and characterize the molecule's unique electronic character.

TL;DR: The dehydrogenative coupling of single porphines to graphene edges on the same metal substrate as used for graphene synthesis is demonstrated and the concomitant metallation of the macrocycle with substrate atoms and the axial ligation of adducts are succeeded.

TL;DR: How specific molecular functionalities can be applied to tailor coordination architectures is disclosed and the potential of Cu as coordination center in such low-dimensional structures on surfaces is highlighted.

TL;DR: It is found that annealing to temperatures between 300 and 320 °C leads to both desorption of iron phthalocyanine molecules from the surface and their agglomeration, and spectroscopy indicates a modified substrate-adsorbate interaction upon annealed with a shortened bond distance.

TL;DR: Temperature-induced dehydrogenative coupling between unsubstituted free-base porphine units and their attachment to graphene nanoribbons on a well-defined Ag(111) support are scrutinized by bond-resolved scanning probe microscopy techniques.
