Bromine atom introduction improves F– sensing ability of indolo[3, 2-b]carbazole-salicylaldehyde-based fluorescence turn-on sensor Heavy-atom effect usually quenches fluorescence, but scarcely enhances it. Herein, fluorescence turn-on sensors without or with bromine atom for F– detection are presented, achieving fast response time within 1 min, and the LODs of 1.9×10-7 and 8.5×10-8 M, reflecting the halogen atom introduction is beneficial for F– detection ability improvement.
