Fluctuating electron-transfer rates, both forward and back (see picture), were measured at the single-molecule level for a triphenylamine–perylenediimide donor–acceptor dendrimer. These fluctuations, reminiscent of those seen for forward electron transfer in some large biomolecules and so far not documented for synthetic systems, are induced by the local environment and conformational changes in the dendrimer.
