Abstract
Langmuir–Blodgett (LB) films from pure ytterbium bisphthalocyanine (YbPc2) and mixtures of YbPc2 and stearic acid have been produced, whose cyclic voltammetric response displays a redox activity strongly dependent on the scan rate and film thickness. Successive redox reactions are accompanied by color variations upon small changes in the electrode potential range which make these films promising for multi-color devices.
