At an acidic pH, cytosine‐rich DNA strands can form i‐motif tetramers. Pillar‐like DNA structures are self‐assembled with such i‐motifs as the central stems. The central stem has some overhanging structures that can enable hybridization with complementary units by Watson–Crick pairing and, thus, multiple i‐motifs can join to form the pillar.
