Abstract
Unusually high kinetic order was observed in self-organized Sc3+-promoted electron transfer from tris(2-phenylpyridine)iridium(III) [Ir(ppy)3] to p-benzoquinone (Q) in propionitrile, third-order with respect to the concentration of Sc3+ and second-order with respect to the concentration of Q, to produce a π-dimer semiquinone radical anion complex that is triply bridged by three Sc3+ ions (Q•--3Sc3+-Q).
