Resorufin-Based Colorimetric and Fluorescent Probe for Selective Detection of Mercury (II)

Abstract

: Environmental pollution crisis, particularly mercury ions (Hg 2+ ) contamination, seriously threatens the health of all living organisms. Many studies have shown that even extremely low concentrations of Hg 2+ can rigorously damage living organisms. Therefore, it is very much needed for real-time detection of Hg 2+ . To tackle mercury contamination and for its detection, we herewith proposed an intelligent design of a new fluorescent ‘turn-on’ probe, which was prepared based on the mercury-promoted hydrolysis of vinyl ether moiety. The probe rapidly reacted with mercury ions and showed good selectivity over other metal ions. Hg 2+ and other metals ions (100 µ M) in CH 3 CN/HEPES buffer solution (1:1, v / v , 0.1 M, pH = 7.4); excitation wavelength = 560 nm, emission wavelength = 585 nm.
