Chiral Recognition of Tetrahelicene Dicarboxylic Acid by Linear Dextrins

Abstract
Recognition of the helicity of 1,12-dimethylbenzo[c]phenanthrene-5,8-dicarboxylic acid (1) by linear oligosaccharides has been studied by 1H NMR spectroscopy and capillary zone electrophoresis. Both methods, clearly indicate that maltotetraose, maltopentaose, maltohexaose, and maltoheptaose selectively complex with the (M)-isomer of 1 as a guest through hydrogen-bonding interaction in water.
