title: Colorimetric and fluorometric detection of cationic surfactants based on conjugated polydiacetylene supramolecules.
abstract: The polydiacetylenes derived from a hydroxybenzaldehyde substituted diacetylene monomer display a unique colorimetric change (blue to red) and large fluorescent enhancement in the presence of cetyl trimethylammonium salt.
