内容摘要：
Two quadruply bonded dimolybdenum coordination building blocks, linked by a variety of organic bridging ligands, have been used to create novel molecular diodes.  By taking advantage of the unique structural, spectroscopic and electrochemical features of a dimetal unit, such as metal-metal bond order, MLCT and MMCT transitions and cyclic voltammogram, electron coupling interaction between the two [Mo2] of the molecules of this type has been studied,  which reveals the significant impact of bridging space, conjugated linkage and donor atoms on intramolecular electron transfer. It has been found that sulfur atom, as serving as a donor from the linker, makes greater contribution for the enhancement of conductance of a single metal-organic molecular transistor. Synthetic chemistry, physical study and electron transfer theory are the core of the research, which aims at the conceptual design of molecular electronics e.g., molecular wire, switch and rectifier.
