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.
