| 中文摘要:合成了两个酰腙类荧光探针1和2，在DMSO-H2O(7∶3,体积比)体系中，两者分别在 478 nm和 460 nm处对Al3+具有较好的荧光选择识别作用。Jobs法、核磁滴定、质谱分析表明，探针1和2与Al3+的配位比均为1∶2，且对Al3+的检出限分别为9.58×10-8 mol/L和6.52×10-8 mol/L。同时提出了探针1和2对Al3+的荧光传感机理。实际应用研究表明，探针1和2可用于河水和自来水中一定浓度范围内Al3+的检测。 |

| Abstract:Two acylhydrazone based fluorescent probes 1 and 2 were synthesized.Probes 1 and 2 both showed an excellent selectivity toward Al3+ in DMSO-H2O(7∶3,by volome) solution at emission wavelengths of 478 nm and 460 nm,respectively.The stoichiometric ratios of 1∶2 for the Al3+ complexes were determined by Jobs plots,1H NMR titration experiments and LC-MS analysis.The detection limits of probes 1 and 2 for Al3+ were found to be 9.58×10-8 mol/L and 6.52×10-8 mol/L,respectively.The fluorescent sensing mechanisms for probes 1 and 2 to Al3+ were proposed.Furthermore,the applied research revealed that the probes 1 and 2 could be used for the detection of Al3+ in river water and tap water samples. |
