Abstract

Organometallic conjugated complexes have become an important type of stimuliresponsive materials because of their appealing electrochemical properties and rich photonic electronic and magnetic properties They are potentially useful in a wide range of applications such as molecular wires molecular switches molecular machines molecular memory and optoelectronic detections This review outlines the recent progress on the molecular design of carbometalated ruthenium and osmium complexes and their applications as redoxresponsive materials with visible and nearinfrared NIR absorptions and electron paramagnetic resonance as readout signals Three molecule systems are introduced including the symmetric diruthenium complexes metalamine conjugated bicenter system and multicenter redoxactive organometallic compounds Because of the presence of a metalcarbon bond on each metal component and strong electronic coupling between redox sites these compounds display multiple reversible redox processes at low potentials and each redox state possesses significantly different physical and chemical properties Using electrochemical potentials as input signals these materials show reversible NIR absorption spectral changes making them potentially useful in NIR electrochromism and information storageThis work was supported by the National Natural Science Foundation of China 21271176 21472196 21521062 21501183 the Ministry of Science and Technology of China 2012YQ120060 and the Strategic Priority Research Program of the Chinese Academy of Sciences XDB 12010400
