文摘

An ultrasensitive fluorescence “turn-on” assay for Cu2 + based on p-dimethylaminobenzamide-based derivative was presented. The probe exhibits excellent selectivity and a very high tolerance to other common ions by the naked eye and fluorescence spectra. The assay was applied to detect Cu2 + on the test kits and in living cells. Compound BDIH showed a very low background.
