在ITO电极表面制备了具有氧化还原活性胺取代基和三个羧酸基的环金属化钌配合物的自组装单层膜。所得薄膜具有低电化学电位输入和高近红外吸光度输出的三态电致变色开关。由于每种氧化态的保留时间都很长，这些薄膜已被用于在分子尺度上展示具有高开/关比的表面受限触发器记忆功能。
Self-assembled monolayer films of a cyclometalated ruthenium complex with a redox-active amine substituent and three carboxylic acid groups have been prepared on ITO electrode surfaces. The obtained thin films show three-state electrochromic switching with low electrochemical potential inputs and high near-infrared absorbance outputs. Thanks to the long retention time of each oxidation states, these films have been used to demonstrate surface-confined flip-flop memory functions with high ON/OFF ratios at the molecular scale.
