【Abstract】 A novel carbazole derivative 9-{ 2-[3-( 2-pyridyl)-1H-pyrazolyl] ethyl }-9H-carbazole was synthesized. This product was confirmed by1 HNMR,13CNMR. The molecular recognition properties was investigated by fluorescence titration and UV titration. The results indicated that this compound exhibited excellent selectivity for Fe3 +,Cu2 +and immune ability for other metal ions. The complexes were composed of 2∶ 1 host and guest molecules. This compound had potential application in sewage detection.更多还原
