Abstract:
Triethyl indolizine-1,2 ,3 -tricarboxylate 3( compound 3) was prepared and characterized by IR,1H NMR. Ultraviolet spectroscopy studies showed the maximum absorption peak at 325 nm. The fluorescence spectra of the compound in different pH buffer solutions were studied. The results indicated that the fluorescence properties were affected apparently by the pH value. With the increasing of the pH, the fluorescent intensity of compound 3 could be increased, and the emission wavelength was blue shifted. The influence of different metal ions was measured, so as to find compound 3’s recognizing properties on some metal ions. We find fluorescence can be decreased evidently by the copper ions, so compound 3 is promising to be the fluorescent probes for copper ions.
