Solvent-Driven Synthesis of DNA-Based Liquid Crystalline Organogels with Extraordinary Stretchability, Self-Healing, and Higher-Order Structural Assembly.

ABSTRACT: The fabrication of liquid crystalline (LC) organogel via supramolecular interactions between Deoxyribonucleic acid (DNA) and lyotropic cationic surfactant containing cyanobiphenyl moiety is reported. The fabricated organogel endows dominantly viscous behavior in dimethyl sulfoxide (DMSO) and elastic behavior in n-propanol (n-PrOH), respectively. By judiciously controlling the viscosity, DMSO organogels can be drawn to form a fiber with an elongation of up to 4.6 × 10³%, emphasizing extraordinary stretchability. Higher-order structures, such as yarn and a co-alignment matrix for anisotropic particles, can be produced by assembling a single fiber. On the other hand, free-standing n-PrOH organogels demonstrate a remarkable storage modulus of 10⁵ Pa and manifest self-heal
