[11]Anthrahelicene on TiO2 surfaces

► [11] anthrahelicenes ([11]AHs) on TiO2(110) and TiO2(011) ►. [11]AHs on the (110) face form ordered island containing two mirror domains having a quasi-hexagonal lattice structure. ► On both the (110) and the (011) faces, single molecules are observed with sub-molecular resolution.
