Complementary quadruple hydrogen bonding in supramolecular copolymers.
This paper describes a supramolecular copolymer based on quadruple hydrogen bonding between self-complementary ureido-pyrimidinones and complementary 2,7-diamido-1,8-naphthyridines. In contrast to previously reported polymer systems solely based on complementary hydrogen-bonding units, these polymers retain a high DP over a broad composition range.
