| 英文摘要 | A tetra(pyrid-2-yl)-pyrazine-bridged cyclometalated diosmium complex 1(PF6)(2) with two distal redoxactive organic amine substituents has been synthesized and characterized. This complex displays four consecutive and separated anodic redox waves at +0.24, +0.38, +0.64, and +0.71 V vs. Ag/AgCl. Upon stepwise oxidation, four-step absorption spectral changes in the visible to near-infrared region have been observed. The different redox states of 1 (1(2+) through 1(6+)) can be distinguished by the significantly different absorption spectra in the visible and near-infrared region. DFT calculations of 1(3+). show that the spin is delocalized on both osmium-amine components. (C) 2015 Chinese Chemical Society and Institute of Materia Medica, Chinese Academy of Medical Sciences.
