A new naphthalene derivative receptor (L) was synthesized and characterized with common spectroscopic methods. L exhibited a strong fluorescence enhancement in the presence of trace amounts of Pb(2+), attributable to photoinduced electron transfer (PET) effect, which also displayed high selectivity over a series of other metal cations (Na(+), K(+), Cs(+), Mg(2+), Ba(2+), Cr(3+), Mn(2+), Fe(3+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+) and Ag(+)) in acetonitrile/H2O (9:1, v/v) mixture.
合成了一种新型萘衍生物受体（L），并用常见光谱方法对其进行了表征。L在痕量Pb(2+)存在下表现出强烈的荧光增强，这归因于光诱导电子转移（PET）效应，在乙腈/水（9:1，v/v）混合溶液中，它对一系列其他金属阳离子（Na(+)、K(+)、Cs(+)、Mg(2+)、Ba(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。
