文摘

Single-electron transfer (SET) between donor-acceptor complex PTZ-TCBQ (phenothiazine锛歵etrachloro-p-benzoquinone聽=聽1/1) and thiol-stabilized gold nanoclusters Au₂₅(SC₂H₄Ph)₁₈^{鈭?/sup>TOA+ (abbreviated as Au₂₅鈭?/sup>) is firstly researched here. Cyclic voltammetry (CV), UV-vis spectroscopy, electron spin resonance (ESR) and nuclear magnetic resonance (NMR) are utilized to study their electron transfer reaction. The characteristic results show only one-electron transfer from Au₂₅鈭?/sup> to the complex, and the excess amount of PTZ-TCBQ complex cannot oxidate Au₂₅0 further as 1HNMR observed. So those results indicate that this well defined gold nanoclusters with a molecular-like redox behavior as an electron donor can be applied as a solar photocatalytic nanomaterial, SET catalyst and聽so on.}
