Abstract

original image

The dimers of rhodocenes and mixed cyclopentadienyl/arene Group 8 species are air-stable, but may be used to n-dope materials with electron affinities as low as 2.8 eV. Monitoring these reactions in solution by UV/Vis spectroscopy indicates that two different mechanisms are possible, depending on the dimer in question, the acceptor, and the experimental conditions. In the case of [{RuCp*(C6H3Et3)}2] and 6,13-bis[tri(isopropyl)silylethynyl]pentacene (shown) the reaction proceeds by rate-determining electron transfer from dimer to acceptor, followed by cleavage of the dimer cation. For more details see the Full Paper by S. R. Marder, S. Barlow et al. on page 14760 ff.
