Transforming Surface Coordination Polymers into Covalent Surface Polymers: Linked Polycondensed Aromatics through Oligomerization of N-Heterocyclic Carbene Intermediates

Isomerize and polymerize! Thermally induced tautomerization of the N‐heteropolycyclic 1,3,8,10‐tetraazaperopyrene to a Wanzlick‐type carbene intermediate on a Cu(111) surface leads to covalently linked polyaromatic chains, which can be mechanically manipulated. The pictures show the respective struc...

Zusammenfassung:Isomerize and polymerize! Thermally induced tautomerization of the N‐heteropolycyclic 1,3,8,10‐tetraazaperopyrene to a Wanzlick‐type carbene intermediate on a Cu(111) surface leads to covalently linked polyaromatic chains, which can be mechanically manipulated. The pictures show the respective structures superimposed on the STM images.
