Overruled! The self‐assembly of a novel group of fused donor–acceptor molecules ( 1 ) comprising hexaazatriphenylene and tetrathiafulvalene branches was studied by STM at the liquid/solid interface. A 2D assembled chiral porous network with C 3 symmetry was found, which is dictated by strong interactions of the extended π‐conjugated cores of the fused units with the HOPG substrate overruling the directional forces of alkyl chains.
