Abstract

A flexible viologen carboxylic acid derivative forms single- and triple-stranded helices by hydrogen-bonding interactions, and undergoes pH-triggered helical transformation by a water-mediated solid-state conversion (see picture). This transformation is accompanied by a fluorescence signal change that can be directly observed by the naked eye under a UV lamp.
