Hydrogen-bonded helices in crystals with prescribed organization

Radu Custelcean, Michael D. Ward

Research output: Contribution to journalArticlepeer-review


Like spiral staircases connecting the floors of a building, twisted chiral organic "pillars" link hydrogen-bonded guanidinium sulfonate sheets and produce extended supramolecular helices (see picture) that wind through crystals with predictable three-dimensional architectures.
