A new macrocyclic nano-chemosensor (L) was synthesized and characterized by common spectroscopic methods. Spectral properties of fluorescent macrocycle L were studied either as solution in ethanol or as insoluble nanoparticles in aqueous buffer solution. The nano-chemosensors with size about 40nm were prepared by nanoprecipitation method. The influence of metal cations such as Na(+), K(+), Cs(+), Mg(2+), Ba(2+), Al(3+), Pb(2+), Cr(3+), Mn(2+), Fe(3+), Fe(2+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Cd(2+), Hg(2+) and Ag(+) on the spectroscopic properties of the chemosensor in aqueous buffer solution were investigated by means of emission spectrophotometry. The macrocycle was found to be as an effective fluorescence sensor for Cs(+) ions.
合成了一种新型大环纳米化学传感器（L），并通过常用光谱方法对其进行了表征。荧光大环L的光谱性质在乙醇溶液中或在水性缓冲溶液中的不溶性纳米颗粒状态下进行了研究。通过纳米沉淀法制备了尺寸约为40nm的纳米化学传感器。采用发射分光光度法研究了Na(+)、K(+)、Cs(+)、Mg(2+)、Ba(2+)、Al(3+)、Pb(2+)、Cr(3+)、Mn(2+)、Fe(3+)、Fe(2+)、Co(2+)、Ni(2+)、Cu(2+)、Zn(2+)、Cd(2+)、Hg(2+)和Ag(+)等金属阳离子对水性缓冲溶液中化学传感器光谱性质的影响。发现该大环是一种有效的Cs(+)离子荧光传感器。
