Electroreductive deposition of Au clusters modified with an anthraquinone derivative

Anthraquinone derivative-modified Au clusters prepared by a substitution re action of octyl thiolate-covered Au clusters with 1-(1,8-dithiaoctyl)anthra cene-9,10-dione undergo a two-step one-electron reduction in aprotic solven ts, resulting in the formation of an electroactive thin Au cluster film. Co mposite film formation is achieved by a combination of oxidative and reduct ive electrodeposition of biferrocene derivative-modified and anthraquinone derivative-modified Au clusters, respectively.
