Beyond Symmetric Motifs: Asymmetric Small-Molecule Recognition Directs a New Poly(adenine) Assembly
DNA/small-molecule hybrid materials provide a powerful route to reprogram nucleic acid structures without covalent modification. However, to date only two small molecules have been shown to direct such assemblies, both relying on symmetric hydrogen-bonding faces. Here, we report that 3-methylxanthine (3MeX), a purine...
