摘要 含蒽酰亚胺基团的化合物N-(2-(6-氨基吡啶))-9-蒽酰亚胺(L1)对Fe3+表现出灵敏的荧光增强响应.L1的衍生物N,N-′(2,6-吡啶基)-二(9-蒽酰亚胺)(L2)对Hg2+在紫外-可见吸收光谱和荧光光谱上显示了良好的识别性.即使在其它金属阳离子存在下,L1和L2分别对于Fe3+和Hg2+仍然表现出较好的选择性. Two synthesized compounds, N-（6-aminopyridine-2-yl）-9-anthracenecarbonamide （L^1）and N, N＇- （pyridine-2,6-yl）-bis（9-anthracenecarbonamide） （L^2） are found to show good sensitivity and selectivity to Fe^3＋ and Hg^2＋ ions, respectively. L^1 shows highly sensitive response to Fe^3＋ on fluorescence spectrum. The recognition of L^2 to Hg^2＋ could be achieved by using absorption and flu-orescence spectra. The effect of the presence of other metal ions on sensing for the aim ions were studied too. In addition, the eoordination models of these two compounds with metal ions were sug-gested.
