Electroreductive Deposition of Au Clusters Modified with an Anthraquinone Derivative

Anthraquinone derivative-modified Au clusters prepared by a substitution reaction of octyl thiolate-covered Au clusters with 1(1,8-dithiaoctyl)anthracene-9,10-dione undergo a two-step one-electron reduction in aprotic solvents, resulting in the formation of an electroactive thin Au cluster film. Composite film formation is achieved by a combination of oxidative and reductive electrodeposition of biferrocene derivative-modified and anthraquinone derivative-modified Au clusters, respectively.
