在含有Fe(III)-柠檬酸盐络合物的PAA水溶液体系中，通过改变Fe(III)/F(II)离子的氧化还原状态，实现了氧化还原响应型凝胶-溶胶/溶胶-凝胶转变。这种可逆的转变可以用Fe(III)离子显色来表示，只要有足够的柠檬酸就可以重复多次。
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.
