摘要：

We have demonstrated a method for fabricating C-60 overlayers with controlled spacing and chirality by reactive coadsorption with the aromatic molecule acridine-9-carboxylic acid (ACA). Structural control is achieved by the mismatched symmetries of the coadsorbates, as well as specific intermolecular and adsorbate-substrate interactions. The resulting supramolecular structure has a C-60 period nearly three times as large as the normal C-60 2D packing of 1 nm and exists in enantiopure domains with robust chirality.
