Description

technical field [0001] The invention relates to the technical field of molecular wires, in particular to a ferrocene and ruthenium acetylene terminal compound bridged by a conjugated ligand and a preparation method and application thereof. Background technique [0002] The traditional silicon-based production technology has almost reached the limit of semiconductor materials, and further improving the lithography precision is facing great challenges both in theory and in processing technology. In recent years, scientists have begun to discover that the development of molecular electronics and the construction of molecular devices and molecular circuits are fully expected to break through the physical limits of traditional devices. As the main component of molecular electronic devices, organic linear molecules have developed rapidly in the design and construction of molecules and electrical properties, such as electrical conductivity and photoelectric properties, and many new...
