Self-Assembly at Interfaces

Book chapter, 2016

Due to the microscopic size of single-molecule components, it is impractical to assemble a large number of single-molecule components via direct top-down manipulation. Instead, self-assembly methods, meaning spontaneous ordering and organization of molecules without direct human intervention, are proposed as the most feasible way of building up multiple single-molecule devices [1]. The self-assembly process is directed by weak interactions. In this chapter, we will introduce the basic concepts of self-assembly and put it into a context of single-molecule electronic devices. We will discuss mechanisms of formation of self-assembled monolayers and how typical single-molecule components interact with surfaces. Finally, we will present some recent developments in electrode materials using single molecules.
