Abstract:
Herein we report the first example of a difluoroboron dibenzoyl based fluorescent probe for Cd(2+) detection. The probe displays high selectivity and sensitivity toward Cd(2+) over Zn(2+) in aqueous solution under physiological conditions. Fluorescence imaging experiments demonstrate its potential application for detecting Cd(2+) in living cells.
