摘要
The AM1 and ab initio calculated geometries of Mobius strips formed by imparting one, two or three twists to cyclacenes of various lengths reveal a localisation of the twist over 2-4 benzo rings. Various properties of these systems are reported, including the geometries, the form of the highest occupied molecular orbitals, the electrostatic potential, and the charge distributions in neutral, 6+ and 6- forms of these molecules. Factors influencing the localising tendency are discussed.
