A new naphthalene derivative receptor (H2L) was synthesized. The chemosensor (H2L) exhibited a strong fluorescence enhancement in the presence of trace amounts of Al(3+), attributable to chelation-enhanced fluorescence (CHEF) effect, which also displayed high selectivity over a series of other metal cations (Na(+), K(+), Cs(+), Mg(2+), Ba(2+), Pb(2+), Cr(3+), Mn(2+), Fe(3+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+) and Ag(+)) in ethanol.
合成了一种新型萘衍生物受体（H2L）。该化学传感器（H2L）在痕量Al(3+)存在下表现出强烈的荧光增强，这归因于螯合增强荧光（CHEF）效应，并且在乙醇中对一系列其他金属阳离子（Na(+)、K(+)、Cs(+)、Mg(2+)、Ba(2+)、Pb(2+)、Cr(3+)、Mn(2+)、Fe(3+)、Fe(2+)、Co(2+)、Ni(2+)、Cu(2+)、Zn(2+)、Cd(2+)、Hg(2+)和Ag(+)）也表现出高选择性。
