Abstract

Abstract : Probe2a exhibiting high sensitivity, good selectivity, wide pH range, lower detection limit, and rapid detection for Al 3+, probe2a was applied for the successful detection of Al 3+ in water samples, food samples and HeLa cells. Abstract : Three novel β-pinene-based fluorescent probes2a–2c were designed and synthesized for the selective detection of Al 3+ . Probe2a showed higher fluorescence intensity toward Al 3+ than the other two compounds. Probe2a determined the concentration of Al 3+ with a rapid response time (45 s), wide pH range (pH = 1–9), excellent sensitivity (LOD = 8.1 × 10 −8 M) and good selectivity. The recognition mechanism of probe2a toward Al 3+ was confirmed by 1 H NMR, HRMS and DFT analysis. Probe2a was successfully used as a signal tool to quantitatively detect Al 3+ in food samples and environmental water samples. Furthermore, probe2a was successfully utilized to label intracellular Al 3+, indicating its promising applications in living cells.
