摘要
(Chemical Equation Presented) Two become one: An AB-type monomer containing both 2-ureido-4[1H]-pyrimidinone and 2,7-diamido-1,8-naphthyridine quadruple hydrogen-bonding moieties is obtained by selective olefin cross metathesis. This monomer addresses the issue of stoichiometric imbalance in the self-assembly of AA + BB-type supramolecular polymers. Moreover, as the linker between both motifs is quite flexible, this monomer exists as a monocycle at low concentrations. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
