摘要：

One hand is better than two! Chirality transfer from the single molecule into a two-dimensional layer is investigated by STM. The supramolecular handedness in homochiral heptahelicene layers, generated on a single-crystal surface (see picture), results from the orientations of next-neighbor molecules. The intermolecular interaction is dominated by steric repulsive forces between the rigid helices, causing a direct transfer of chirality.
