ABC triblock copolymers bearing adenine- and thymine-functionalized external blocks self-assembled into long-range, ordered lamellar microphase-separated morphologies on non-patterned substrates. Intermolecular hydrogen bonding formed thymine-adenine triplets promoted self-assembly well-defined lamellae consisting of poly(n-butyl acrylate) soft domains complementary nucleobase hard domains, while duplets contributed to superior mechanical properties.
