Heptylviologen was intercalated into V2O5 xerogel films by chemical and electrochemical methods. Chemical intercalation occurred by the reaction of a V2O5 xerogel film with a propylene carbonate (PC) solution of heptylviologen (HV). The viologen was present as a solvated form in the interlayer of V2O5 gel. A reversible intercalation-deintercalation of HV was carried out by electrochemical reduction-oxidation of the V2O5 xerogel film in a PC solution of HV. The electrochemical intercalation took place only when the interlayer region of V2O5 gel was expanded by PC.
