Abstract:
From scanning tunneling microscopy (STM) images of rationally designed helical polymers with a pattern of π-π stacking, we successfully identified the single- and double-helical superstructures. The STM images of the helical structures revealed the smallest helical architecture (diameter ca. 1.3 nm) that has been seen so far. Furthermore, the interconversion of single and double helices was further underpinned by experimental analyses. Significantly, the formation of double helices induced different supramolecular chirality to that observed for the single helices.
