and microanalysis as well as by mass spectrometry. Comparative studies on the effect of various metal cations such as Cr(III), Cu(II), Cu(I), Zn(II), Cd(II), Pb(II), Na(I), Ni(II), Co(II), Ba(II), Fe(II), Fe(III), Al(III), La(III), Au(III), Mg(II), Cs(I), Ca(II), Hg(II), K(I), Mn(II) and Ag(I) on the fluorescence of L were investigated in aqueous ethanol. The macrocycle was found to be a sensitive and
合成了一种带有两个荧光团萘基团的新型 N 3 O 2氮杂冠大环配体 ( L ),并通过红外、1 H 和13 C NMR、DEPt-135、HSQCGP、微量分析以及质谱对其进行了表征。Cr( III )、Cu( II )、Cu( I )、Zn( II )、Cd( II )、Pb( II )、Na( I )、Ni( II )等多种金属阳离子作用的比较研究, Co( II ), Ba( II ), Fe( II ), Fe( III ), Al( III), La( III ), Au( III ), Mg( II ), Cs( I ), Ca( II ), Hg( II ), K( I ), Mn( II ) and Ag( I ) 对荧光的影响L在乙醇水溶液中进行了研究。发现大环化合物是一种灵敏且具有选择性的 Mg 2+荧光化学传感器。结合常数值确定为 1.36 × 10 5 M -1以及
