Supramolecular polymers, relying on reversible intermolecular interactions, promise a wide range of applications, including optoelectronic materials, self‐healing materials, and biomedical delivery materials. Among potential molecular candidates, DNA strands act as an excellent platform. DNA has a well‐established secondary structure (double helix), and its intermolecular interactions can be readily thermodynamically engineered and kinetically controlled. Extensive studies have demonstrated that various DNA motifs can polymerize/assemble into large polymers with different topology, geometry, and dimensionalities. Most of the reported polymerization is driven by hybridization of DNA strands. Herein, we report a novel system of DNA supramolecular polymerization that is driven by DNA base stacking. The polymerization has been confirmed by native polyacrylamide gel electrophoresis (PAGE) and atomic force microscopy (AFM). We believe that this work will expand the toolbox for DNA supramolecular polymerization and would, with further development, increase further control of DNA supramolecular polymerization.
