P-34 Mechanism Analysis of Copper(II) Ions Interacting with Dimethylaminocyanostilbene
Abstract
Previous research had suggested that the fluorescence of dimethylaminocyanostilbene (DCS) is selectively quenched by copper(II) ions. This study aimed to elucidate the fluorescence quenching mechanism and to explore its potential application to screen for copper ions in water samples. A spectroscopic Job Plot analysis was used to find the ratio of DCS and copper(II) ion binding. Additionally, DCS was mixed with various buffered metal ion solutions to reveal any ion-dependent and/or pH-dependent fluorescence response. NMR analysis of DCS and various buffered copper(II) solutions was also performed to further study the interaction between copper(II) ions and DCS.
