Abstract :
A total-energy electronic-structure calculation is used to explore energetics and electronic structures of one-dimensional chains of recently fabricated C60 derivatives, each having a ‘shuttlecock’ shape. We find that a column of shuttlecocks is a novel π electron network, where each C60 separates into a C5 ring and a C50 cage. The segmentation results in narrow energy bands around the energy gap leading to a localized spin on each molecule, where the spins are predicted to be antiferromagnetic due to a kinetic exchange effect.
