Abstract

A study was conducted to define a new strategy for the introduction of thermally stable ionic sites to block copolymers through hydrogen bonding. Hydrogen bonding exhibited lower enthalpies and greater specificity, which enabled molecular recognition and lower melt viscosities, using hydrogen-bonding arrays, such as ureido pyrimidones (UPy) and nucleobase pairs. Novel hydrogen-bonding triblock copolymers containing adenine, were synthesized through nitroxide-mediated polymerization. A novel difunctional initiator, which does not introduce hydrolytically unstable ester links that lead to molecular weight loss, permitted the formation of symmetric outer blocks, reduced the number of monomer additions, and enabled a single crossover reaction.
