چکیده

Copper ions are important biologically and environmentally—Cu is the third most abundant essential transition element in the body. However, too much copper has been connected to several diseases, and is also a significant environmental metal pollutant (Liu and Wu, 2011). Detection of copper has been studied in the field of analytical chemistry because of its toxicity to humans, bacteria, and aquatic environments at high concentrations (Zhao et al., 2009). The goal of my project is to study the optical activity of the donor-acceptor stilbene dimethylaminocyanostilbene (DCS) with Cu (see Figure 1). In a rapid, high concentration screen, DCS showed significant and selective fluorescent quenching in the presence of high Cu concentrations indicating its potential as a copper ion sensor.
