The resulting porous materials possess atomic precision for several potential applications that rely on crystalline lattices and cavities. Herein, we present a rationally designed and self-assembled 3D DNA crystal lattice with hexagonal symmetry. In our design, two 21-base oligonucleotides are used to form a duplex motif that further assembles into a 3D array. The interactions between the strands are programmed using Watson-Crick base-pairing. The six-fold symmetry, as well as the chirality, is directed by the Holliday junctions formed between the duplex motifs. The rationally designed DNA crystal provides a new avenue that could create self-assembled macromolecular 3D crystalline lattices with atomic precision. In addition, the structure contains a highly organized array of well-defined cavities that are suitable for future applications with immobilized guests.
