Popis:	The photoelectrochemistry of a polymer coated electrode exploiting the chromophore bis(maleonitriledithiolato)nickelate(II) to link the redox self-exchange conductor poly(xylylviologen) to the solution couple Fe(CN)63−/4− is described. The diffusion coefficient for the Fe(CN)63−/4− redox couple in the film is 4.2 × 10−9 cm2/s. The system was developed in an attempt to improve on a system where a quaternary ammonium substituted polystyrene/polyvinylpyridine blend films functioned as a good ionic conductor but poor electronic conductor in consequence of the trap states. The expected improvement in electronic conductivity is seen but at the expense of lower ionic mobility. Key words: polyviologen, bis(maleonitriledithiolato)nickelate(II), polymer conduction, photoelectrode.
