Abstract

We present transmission electron beam identification of C₆₀-based polymeric chains in the mixture between Co and C₆₀ simultaneously deposited on (0 0 1) NaCl at room temperature. Estimation of intrachain distances taken from the direct image suggests bridging position of Co atoms between buckyballs. The chains tend to be coupled due to Coulomb interaction between the charged units of the polymers. We have confirmed the charge transfer between Co and C₆₀ detecting 0.6 eV upward shift of C₆₀ LUMO-derived peak in the electron-energy-loss spectrum of mixture. The systematic shifts of energy-loss σ^* peaks imply distortion of C₆₀ cages belonging to the polymeric chains.
