For the fabrication of ordered two dimensional (2D) crystal structure of chiral macromolecules on solid substrates through structural characterization of helical polymers are essential. To address the above issues, the helical structures of poly(diphenylacetylene)s (PDPAs) bearing optically active substituents linked through amide bonds and with a helicity memory have been visualised directly using high resolution atomic force microscopy (AFM). The PDPAs self-assembled into a short-range, ordered 2D monolayer on highly oriented pyrolytic graphite (HOPG) substrates upon exposure to solvent vapour, whose helical pitch and handedness (right- and left-handed) has been revealed for the first time with molecular resolution.
In 2022, we focused on the measurement of the 2D crystal structure of PDPA, which has a simple structure.
