摘要

•HFPNM undergoes fluorescence quenching upon contact with Cu2+.•HFPNM is capable of accurately detecting 100–1000 nmol/L of Cu2+.•HFPNM can still be used as a Cu2+ sensor after 5 cycles of use.•HFPNM have the advantages of high detection sensitivity and environmental friendliness for recycling compared to other Cu2+ sensors.
