ABSTRACT:
A method for bulk separation of single-walled tubular fullerenes (100) based on helicity is provided wherein a solution or suspension of the single-walled tubular fullerenes (100) is flowed onto a crystalline or highly oriented substrate (30). The single-walled tubular fullerenes (100) that flow onto the substrate (30) have a respective longitudinal axis that is aligned with the flow direction (105). The direction of flow (105) is oriented at a predetermined angle with respect to a lattice axis (24) of the substrate (30) for energetically favoring adsorption of a respective plurality of single-walled fullerenes (100) having a tubular contour and a selected helicity. Subsequently, the adsorbed single-walled tubular fullerenes (100) of the selected chirality are removed from the substrate (30).
