Abstract
In the current study, a polydiacetylene (PDA)-based sensor, derived from a chelidamic acid-picolylamine (CP)-substituted diacetylene monomer, displayed a selective colorimetric and fluorometric change in the presence of cadmium (Cd2+) at pH 7.4. The PDA-CP solutions showed a colorimetric change from blue to violet in response to various amounts of Cd2+. The chemosensor also showed a rapid fluorescence turn-on response and significant selectivity to Cd2+ compared with other metallic cations. The Cd2+-selective PDA-based sensor system facilitated the visual detection of Cd2+ in aqueous solution. The Cd2+ detection limit of PDA-CP was reduced to 1.85x10(-5) M.
