Communication: New, inexpensive, stable electrode materials which function on the principle of heterogeneous redox catalysis have been prepared from a mixture of copper phthalocyanine (CuPc) and polytetrafluoroethylene (PTFE) or acrylate/melamine baking varnish. The electrode material can be simply 'painted' on to a substrate and exhibits a greater stability than vapor-deposited layers. As all the materials are readily available applications as synthesis electrodes and in electrochromic displays can be envisaged.
