Reaction scheme and concept. a Reactions of the precursor monomer 5,5,8,8-tetramethyl-5,6,7,8-tetrahydroanthracene-2,3-dicarbonitrile (ADN) with different metal templates (Fe, Gd) on Ag(111), resulting in the formation of iron-naphthalocyanine (Fe-NPc) and gadolinium-supernaphthalocyanine (Gd-SNPc). Using the bare Ag(111) surface as a laterally extended template leads to surface-catalyzed polymerization and formation of poly(benzodiiminoisoindoline), here named polycyanine. b On-surface template approach: control over the topology of the reaction products is achieved by using differently sized metal templates in 2D confinement
