单分子电导测量的最新进展使我们能够了解分子导线的基本导电特性。到目前为止，虽然已经对各种各样的有机分子导线进行了研究，但无机和有机金属分子导线受到的关注要少得多。然而，含有过渡金属原子的分子导线展现出不同于有机导线的有趣特性和功能。这些特性主要源于金属 - 配体的d - p相互作用以及金属 - 金属的d - d相互作用。由于金属原子和支撑配体的丰富组合，分子导线的前线轨道能量可以被精细调节，从而产生高导电性的分子导线。此外，金属配合物独特的电子结构容易受到细微环境变化的影响，这有可能产生功能性分子器件。本文综述了无机和有机金属分子导线单分子电导研究的最新进展。
Recent developments of single-molecule conductance measurements allow us to understand fundamental conducting properties of molecular wires. While a wide variety of organic molecular wires have been studied so far, inorganic and organometallic molecular wires have received much less attention. However, molecular wires with transition-metal atoms show interesting features and functions distinct from those of organic wires. These properties originate mainly from metal-ligand d-p interactions and metal-metal d-d interactions. Thanks to the rich combination of metal atoms and supporting ligands, frontier orbital energies of the molecular wires can be finely tuned to lead to highly conducting molecular wires. Moreover, the unique electronic structures of metal complexes are susceptible to subtle environmental changes, leading to potential functional molecular devices. This article reviews recent advances in the single-molecule conductance study of inorganic and organometallic molecular wires.
