Supramolecular chemistry in two dimensions: self‐assembly and dynamic function

Nanosciences and nanotechnologies using organic molecules rely strongly on bottom‐up fabrication. In particular, versatile methods for control of molecular arrangement at a solid surface, which would include the crucial self‐assembling processes of functional molecules in two‐dimensions, are anticipated. On the other hand, gas–liquid interfaces, such as the air–water interface, provide motional freedom for embedded molecules, leading to novel dynamic functions. We have recently focused on research involving molecular recognition, self‐assembly, and molecular patterning at solid surfaces and at the air–water interface. These research subjects can be collectively categorized as “supramolecular chemistry in two dimensions”. In this feature article, we will briefly outline our recent research activities in self‐assembly and dynamic functionality in two dimensions, including control of molecular arrangement at solid surfaces, two‐dimensional molecular patterning, and dynamic molecular recognition.
