Regulated electrochemistry of viologen-containing Langmuir–Blodgett film prepared by polyion complex technique

Abstract
A polyion-complexed monolayer of a water-soluble viologen amphiphile and poly(acrylic acid) was immobilized as a Langmuir–Blodgett (LB) film on an indium–tin oxide (ITO) electrode; electrochemical reduction of the viologen was found in the LB film and the redox potential was affected by pH.
