      Abstract:

      Redox-responsive gel−sol/sol−gel transition in aqueous PAA system   containing Fe(III)−citrate complex was realized by switching the   redox states of Fe(III)/F(II) ions conjugated with photoreduction   and oxidation. This reversible transition can be indicated   chromatically by the Fe(III) ions and repeated many times as long   as there is sufficient citric acid.
