Abstract

Herein we report the first example of a difluoroboron dibenzoyl based fluorescent probe for Cd²⁺ detection. The probe displays high selectivity and sensitivity toward Cd²⁺ over Zn²⁺ in aqueous solution under physiological conditions. Fluorescence imaging experiments demonstrate its potential application for detecting Cd²⁺ in living cells.
