| 摘 要： | 本文基于Ir(Btp)2(acac)为发光内核,合成了一种外围为萘环的苄醚型树枝状红光铱配合物,并通过NMR、MS和元素分析实验表征了该配合物。利用紫外-可见吸收光谱与磷光光谱实验研究了该配合物对金属离子的识别作用。结果表明:在CH3CN/THF溶液中,仅Hg2+的加入能引起配合物的最大吸收峰和发射峰均发生蓝移,溶液颜色由桔黄色变为浅绿色。该配合物可作为识别汞离子的光化学传感器。

| Abstract: | A Ir(Btp)2(acac) cored red dendrimer with benzyloxy-based dendrons bearing naphthyl peripheral group was synthesized and characterized by NMR,MS and element analysis experiments.The metal ions recognition properties were investigated by absorption and emission spectra.Only upon addition of Hg2+,obvious blue-shifts both in absorption spectra and emission spectra were observed with the color of the CH3CN/THF solution changing from orange-yellow to light green.The results demonstrated that an optical chemo-sen... |
