| 4 | A Highly Selective and Sensitive Fluorescent Chemosensor for Detection of Al^(3+) in Totally Aqueous Media显示文摘A fluorescent chemosensor(1)based on 2-hydroxy-1-naphthaldehyde Schiff-base was developed for the detec-tion of Al^(3+)in 100%aqueous solution.Upon addition of Al^(3+),a significant fluorescence enhancement was ob-served,which was not affected by other metal ions including Na^(+),K^(+),Ca^(2+),Mg^(2+),Mn^(2+),Co^(2+),Ni^(2+),Cu^(2+),Cr^(3+),Ag+,Pb^(2+),Zn^(2+),Cd^(2+),Hg^(2+),Fe^(2+)and Fe^(3+)under weak acid conditions.Moreover,the specific response to Al^(3+)was visible under natural light.The binding mode between 1 and Al^(3+)was clarified by ESI-MS and 1H NMR. | Xiaobo Li Jiayi Chen Enju Wang | 2014 | Chinese Journal of Chemistry2014，32，5： | 0 |
