Polarons in linear chains of fullerenes

Polaron states in linear chains of fullerenes are studied with the use of the generalized model of Su-Shrieffer-Heeger (SSH) for the intermolecular and intramolecular degrees of freedom. Electron charge distributions over the molecular surface and Jahn-Teller distortions of carbon atoms in C₆₀ are calculated self-consistently for linear C₆₀ polymer and C ₆₀ ⁻ polyanion chains. A polaron band narrowing is examined. It is shown that the polymerization of C₆₀ molecules in phase transitions may be caused by the cooperative Jahn-Teller effect. Pis’ma Zh. éksp. Teor.
