Free radicals (Chemistry). ; Electron donor-acceptor complexes. ; Ions.
In this study, the initial charge separation distance and its impact on free radical ion (FRI) formation are investigated in detail. Transient photocurrent techniques together with other spectroscopic methods were used with a series of donors and...
Fluorine forms the strongest single bond to carbon, however, it is well established that transition metals can lengthen and weaken C-F bonds in fluorinated ligands. Described here are studies on the activation of C-F bonds in iridium compounds...
