摘　　要：将香豆素衍生物7-二乙氨基香豆素-3-甲醛(DCC)与UiO-66-NH2通过席夫碱反应共价相连,合成了一种新型荧光探针材料UiO-66-DCC。傅里叶变换红外光谱(FT-IR)、X射线光电子能谱(XPS)、X射线粉末衍射(PXRD)的表征结果表明,DCC与UiO-66-NH2成功相连,获得的UiO-66-DCC保持了UiO-66-NH2结构的完整性。荧光性能实验表明,UiO-66-DCC在乙醇中能够专一地识别Al^(3+)。向UiO-66-DCC的乙醇分散液中滴加Al^(3+)后,UiO-66-DCC的荧光增强了约9.7倍,对Al^(3+)的检出限为0.553μmol/L,其他常见金属阳离子的存在未对UiO-66-DCC检测Al^(3+)造成明显的干扰。A novel fluorescent probe material,UiO-66-DCC,was synthesized by covalently linking a coumarin derivative with UiO-66-NH2 via the Schiff base reaction.The results of Fourier transform infrared spectroscopy(FT-IR),X-ray photoelectron spectroscopy(XPS),and X-ray powder diffraction(PXRD)showed that 7-diethylaminocoumarin-3-carboxaldehyde(DCC)and UiO-66-NH2 were successfully linked,and the obtained UiO-66-DCC maintained the structural integrity of UiO-66-NH2.The fluorescence performance experiments showed that UiO-66-DCC could specifically recognize Al^(3+)in ethanol.After adding Al^(3+)to the ethanol dispersion of UiO-66-DCC,the fluorescence of UiO-66-DCC was enhanced by about 9.7 times,and the detection limit was 0.553μmol/L.The presence of other common metal cations did not significantly interfere with the detection of Al^(3+)by UiO-66-DCC.
