Abstract:
The present invention provides a novel anthracene derivative compound having selectivity to a metal ion. In addition, because a noticeable fluorescence response is shown when an anthracene derivative compound forms a complex with Fe^3+, Zn^2+, and Cu^2+ ions, the anthracene derivative compound may be used as a high sensitive fluorescent sensor to detect Fe^3+, Zn^2+, and Cu^2+ ions. Specifically a fluorescent strength with respect to Fe^3+ is noticeably increased, thus the present invention is more useful because Fe^3+ can be quickly and accurately detected even when mixed with various metal ions.
