제목 Visual detection of cadmium ion based on conjugated polydiacetylenes
초록 In recent years, pollution associated with the presence of heavy metal ions in the environment has been extensively investigated. Among the various heavy metal ions, cadmium (Ⅱ), is one of the most hazardous and carcinogenic metals, because of its widespread use in fields such as metal alloys, electroplating, stains, fertilizers, as well as in rechargeable batteries. In this regard, we present our findings involving the development of a simple and cost-effective sensor for naked-eye detection of Cd2+ that does not require an external power source.
Polydiacetylenes (PDAs) have received increasing attention as smart materials owing to their unique properties.1,2 Upon addition of various stimuli, the blue PDAs can undergo a colorimetric transition from blue to red along with a change from non-fluorescent to fluorescent.
