Abstract

Abstract Cationic aryl triazole oligomers have been synthesized through “click chemistry”. The results show that cationic aryl triazole oligomers adopt a helical conformation in water or in a mixture of water and methanol, but prevail as a random-coiled conformation in methanol. Importantly, circular dichroism spectroscopy and dynamic light scattering experiments revealed that cationic oligomers aggregated intermolecularly to form higher ...
