Abstract
A novel fluorogenic “turn-on” sensor NPP based on naphthalimide and picolinohydrazide units was prepared for highly selective Al 3+ detection. This “signal-on” probe NPP has been efficiently utilized for Al 3+ detection in real samples. • A novel naphthalimide-picolinohydrazide derived optical chemosensor NPP is presented for Al 3+ . • NPP exhibited hypersensitive toward Al 3+ with rapid signal response (1 min). • Limit of detection (LOD) of NPP for Al 3+ was as low as 39 nM. • NPP was efficiently utilized as a promising sensor for Al 3+ detection in real samples. • NPP -coated test strips were successfully applied for quickly monitoring Al 3+ ions in a visible manner. The development of high-selective chemosensors for trace Al 3+ detection in the ecosystem is crucially importance due to its detrimental effects. In this work, a simple Schiff-base fluorescent probe NPP derived from naphthalimide and picolinohydrazide was rationally designed and prepared for efficient detection of Al 3+ . NPP exhibited prominent sensing behaviors toward Al 3+ with low detection limit (LOD) (39 nM), rapid response time (1 min), strong binding affinity (4.02 × 10 4 ), good anti–interference characteristics and visual detection. Binding ratio of NPP -Al 3+ complex was determined to be 1:1 by Job’s plot analysis. In addition, the chelation mechanism of NPP with Al 3+ ions was proposed and substantiated by the density functional theory (DFT) and time-dependent density functional theory (TD-DFT), IR spectrum and 1 H NMR titration experiments. Furthermore, this “signal-on” probe NPP was efficiently utilized as a promising indicator for Al 3+ detection in environmental and biological samples.
