Two new coordination polymers, {[Zn4(DPBT)2(BDC)4]·(H2O)·2(DPBT)}n (1), {[Cd2(DPBT)2(BDC)2]·(DMA)}n (2), have been obtained from the self-assembly of the heterocycle ligand DPBT with different d10 metal ions, in the presence of BDC2− coligand. Interestingly, the emission spectra exhibit that both compounds possess fluorescent turn-on or turn-off sensing behavior for different metal ions. Compared...
A simple and selective spectrofluorimetric method for the determination of trace levels of aluminum has been developed using Alizarin Complexone (AC). Exhibiting absorption and fluorescence changes in the presence of Al 3+ in EtOH–H 2 O solution at pH 4.6, AC could be used as a colorimetric and fluorescent chemosensor for the detection of Al 3+ . In the presence of Al 3+...
