Two-dimensional Molecular Patterning through Molecular Recognition

Abstract
Molecular images for the mixed monolayers composed of guanidinium (G) and orotate (O) amphiphiles on pure water and on aqueous flavin adenine dinucleotide (FAD) solution were taken with an atomic force microscope (AFM). The AFM image of G/O mixed monolayer on FAD showed a periodic pattern composed of two kinds of peaks with different heights, whereas that on pure water showed a periodic peak. The molecular pattern is apparently induced by rearrangement of monolayer components based on specific recognition by FAD template molecule.
