| 摘 要： | 在乙酸酐中用2,9-二甲基-1,10-菲咯啉与水杨醛缩合反应得到2,2′-(1E,1′E)-2,2′-(1,10-菲咯啉-2,9-二基)双(乙烯-2,1-二基)双(2,1-亚苯基)二乙酸酯(探针1);再将其进一步水解得到2,2′-(1E,1′E)-2,2′-(1,10-菲咯啉-2,9-二基)双(乙烯-2,1-二基)二苯酚(探针2)。经1H NMR、13C NMR、IR、MS表征,探针化合物为大共轭结构,发光性能良好。两种探针分别表现出对Cu2+、Ag+不同的荧光猝灭作用,探针2还能识别阴离子F-和AcO-,具有双功能离子检测性能。光谱滴定、等温滴定量热及质谱等测定了配合物组成、作用常数及热力学参数,探针与金属离子的配合为放热反应,作用比为2∶1。 |

| Abstract: | 2,2'-(1E,1'E)-2,2'-(1,10-phenanthroline-2,9-diyl)bis(ethene-2,1-diyl)bis(2,1-phenylene) diacetate (probe 1) was synthesized by condensation reaction in acetic anhydride from 2,9-dimethyl-1,10-phenanthroline and salicylic aldehyde, then hydrolyzed to yield 2,2'-(1E,1'E)-2,2'-(1,10-phenanthroline-2,9-diyl)bis(ethene-2,1-diyl)diphenol (probe 2). The molecular structure of large conjugated were characterized by 1H NMR, 13C NMR, IR and MS. Excellent luminescent properties of probes 1 and 2 showed that different fluorescence quenching effect for Cu2+ and Ag+. Probe 2 with a dual-function ion recognition performance exhibited for F- and AcO- anions. The complexes composition, stability constants, thermodynamic parameters and complexation model were evaluated using spectral titration, isothermal titration calorimetry and mass spectrometry. The complexation of probes and metal ions with 2:1 molar ratio were exothermic reaction. |
