Abstract:

A naphthalimide-based turn-on fluorescent sensor for Fe3+ ion was designed and synthesized, whose receptor comprise piperazine and acetyl aminoquinoline. The results reveal that this novel probe exhibits a high selectivity to Fe3+ ion in neutral buffer aqueous. After silylation, the probe was covalently bonded to the silical particles to be a turn-on fluorescent sensing material, which showes a good linearity (correlation coefficient R2=0.9023) in the range of 20-140 μmol/L of Fe3+ ion.
