将一种含吡啶配体的高价反式二氧合铼（V）配合物成功地固定在ITO（铟掺杂氧化锡）电极上。该配合物在电极表面形成了单层结构，并促进了1-苯基乙醇在二氯甲烷中的电化学催化氧化为苯乙酮。在含有游离配位化合物的CH_2Cl_2溶液中，几乎不发生氧化反应。其他高价金属配合物的固定化将为高活性功能电极的设计提供机会。（© Wiley-VCH Verlag GmbH & Co. KGaA，69451魏因海姆，德国，2004）
A high-valent trans-dioxorhenium(V) complex containing pyridine ligands was successfully immobilized on an ITO (indium-doped tin-oxide) electrode. The complex formed a monolayer structure on the electrode surface and promoted electrochemical catalytic oxidation of 1-phenylethanol to acetophenone in CH2Cl2. Oxidation hardly occurred in CH2Cl2 solution containing the free rhenium(V) complex. Immobilization of other high-valent metal complexes will present opportunities for design of functional electrodes with high activities. (© Wiley-VCH Verlag GmbH & Co.
