Two-Dimensional Helix-Bundle Formation of a Dynamic Helical Poly(phenylacetylene) with Achiral Pendant Groups on Graphite

Two-Dimensional Helix-Bundle Formation of a Dynamic Helical Poly(phenylacetylene) with Achiral Pendant Groups on Graphite

It all makes sense: A dynamically racemic helical polymer crystallizes on graphite upon exposure to an organic solvent vapor, resulting in two‐dimensional helix‐bundle formation. The enantiomeric right‐ and left‐handed helical blocks separated by helical reversals can be directly visualized by AFM w...

Zusammenfassung:It all makes sense: A dynamically racemic helical polymer crystallizes on graphite upon exposure to an organic solvent vapor, resulting in two‐dimensional helix‐bundle formation. The enantiomeric right‐ and left‐handed helical blocks separated by helical reversals can be directly visualized by AFM with molecular resolution.
