Hydrogen bond-induced rigid oligoanthranilamide ribbons that are planar and straight.
[structure: see text] A new series of oligoanthranilamides has been synthesized starting from suitably modified p-phenylenediamine and p-phthalic acid derivatives. Due to strong intramolecular three-center hydrogen bonds, the new oligomers self-assemble into highly stable straight and planar molecular ribbons, which have been characterized by X-ray crystallography and 1H NMR, IR, and UV-vis spectroscopy.
