摘　　要：以CO32-型镁铝水滑石为前体,以有机荧光黄阴离子为客体,采用焙烧复原法和离子交换法,组装得到有机阴离子柱撑水滑石功能材料。并用FTIR、XRD、TG-DSC和分子荧光光度计等手段对样品进行了表征,发现该功能材料的荧光发射波长发生蓝移(约10 nm),且其发光强度比荧光黄明显减弱,表明该功能材料能有效调控有机阴离子的荧光性能。The function material was made by calcined method and ion exchanged method,using CO32-type Mg,Al-hydrotalcite as precursor and fluorescein anion as object.The samples were characterized by XRD,FTIR,TG-DSC and Fluorometry.As a result,the emission wave of the Fluorescein moved to low wave,and the intensity became weak.It showed that the function material could regulate the fluorescence of the organic anion.
