当“自下而上”途径组装器件的理念被提出后，美国科学家费曼继而提出小尺度上的操作和控制物质材料，这两个理念引导下产生的分子电子学成为备受人们关注的交叉性学科。过去的六十年里，分子电子学获得了飞速的发展，尤其是世纪之交的十年可谓是“分子电子学的黄金十年”，科学家们接连得到单原子、单分子尺度上的物理化学性质并付诸应用。然而，分子电子学研究的基本结构单元仍是金属/分子/金属结，而其构筑方法的不稳定性和表征手段不重现及单一性仍然是分子结的构筑和表征研究中面临的主要困境。 本论文工作以构筑稳定分子结为目标，结合机械可控裂结法（MCBJ,MechanicallyControllableBreakJunct...Since the idea of "Bottom-up" approach to assemble devices and the dream of manipulation and control materials in atomic scale by Feynman have been proposed, molecular electronics has become an interdisciplinary science and received much attention. Over the past 60 years, molecular electronics has developed rapidly, especially, went through a "golden period of molecular electronics" of near ten ye...学位：理学硕士院系专业：化学化工学院_物理化学学号：2052012115152
