Abstract
CdSe quantum dots, in the form of colloidal nanocrystals, are bound to the surface of a gold electrode by bisulfide spacer molecules. The distance dependance of the electron transfer rate between the CdSe and the electrode was investigated by a time- resolved optoelectronic method and related to the length r of the spacer molecule 1-3 [Eq. (1) ]. For β, a value of 0.50 ± 0.05 Å-1 was found.
