“…8 In many instances, hydrogen bonded selfassembly produced synergistic effects with ionic interactions, which resulted in unique microphase separated, nanostructured morphologies. 9,10 The versatility of the phosphonium cation and signicance of morphology extend beyond bulk polymer properties. Diblock copolymers containing a phosphonium complexation block and poly(ethylene glycol)-based (PEG) stabilizing block produced colloidally stable polymer-DNA polyplexes most likely due to the formation of complex solution structure.…”

“…[10][11][12] Many controlled polymerization methods provide nucleobasecontaining polymers with well-defined architectures in the earlier literature. Common synthetic strategies to control the polymerization of nucleobase-functionalized monomers have included atom transfer radical polymerization (ATRP), 9,13,14 nitroxide mediated polymerization (NMP), 6,11,15 and ring-opening metathesis polymerization (ROMP). [16][17][18] Reversible addition-fragmentation chain transfer (RAFT) polymerization represents a relatively new and promising method for controlling polymerization of nucleobase monomers due to superior solvent compatibility and functional group tolerance.…”

RAFT polymerization afforded acrylic ABC triblock copolymers with self-complementary nucleobase-functionalized external blocks and a low-Tg soft central block. ABC triblock copolymers self-assembled into well-defined lamellar microphase-separated morphologies for potential applications as thermoplastic elastomers. Complementary hydrogen bonding within the hard phase facilitated self-assembly and enhanced mechanical performance.

“…Long and co‐workers used the same strategy to attach discrete cationic tetraalkylphosphonium units to triblock copolymers . In a more recent study, they have evaluated the role of nucleobase pairing as a driving force in the self‐assembly and microphase separation of triblock polyacrylate systems .…”

Dynamic and reversible non‐covalent interactions endow synthetic systems and materials with smart adaptive functions that allow them to response to diverse stimuli, interact with external agents, or repair structural defects. Inspired by the outstanding performance and selectivity of DNA in living systems, scientists are increasingly employing Watson−Crick nucleobase pairing to control the structure and properties of self‐assembled materials. Two sets of complementary purine‐pyrimidine pairs (guanine:cytosine and adenine:thymine(uracil)) are available that provide selective and directional H‐bonding interactions, present multiple metal‐coordination sites, and exhibit rich redox chemistry. In this review, we highlight several recent examples that profit from these features and employ nucleobase interactions in functional systems and materials, covering the fields of energy/electron transfer, charge transport, adaptive nanoparticles, porous materials, macromolecule self‐assembly, or polymeric materials with adhesive or self‐healing ability.
