摘要：

Trinuclear ruthenium clusters attached to Au nanoparticles can be partially reduced to form mixed-valence nanoclusters. The nanoparticles are synthesized using a modified Brust method. IR-SEC shows dynamic coalescence of the stretching vibrations of the carbonyls, v(CO), indicating the electron transfer between Ru clusters attached via a π-conjugated bridge to NPs occurs on the picosecond timescale. Simulation of IR spectra gives k et on the order of 10 11 s -1. © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
