Abstract The increasing attention devoted to triangulenes and their heteroatom derivatives inspired us explore a divergent synthesis of heteroatom‐centered 4,8,12‐triazatriangulenes, which involved the preparation nitrogen‐containing macrocyclic precursor subsequent central introduction by electrophilic C−Li C−H substitution. boron‐centered triangulene has planar structure unlike bowl‐shaped phosphorus‐ silicon‐centered triangulenes. described synthetic procedure can be used fabricate broad range attractive functional materials, for example, organic light‐emitting diodes, based on
