Özet
A new available multi-analyte fluorescent sensor based on a bisphenol A-quinoline conjugate (BFQ) was synthesized in two facile steps and was characterized systematically. BFQ exhibited an effectively selective and sensitive recognition toward Zn(2+)and Al3+ cations in EtOH-H2O (v/v = 9/1) over other cations and F- anion in CH3CN over other anions with remarkably enhanced fluorescent intensities. According to the quantum yield (I broken vertical bar) measurements, BFQ-Zn2+, BFQ-Al3+ and BFQ-F- complexes showed 16, 22 and 30 times higher I broken vertical bar values than BFQ, respectively. The complexation properties of BFQ with Zn2+, Al3+ and F- ions were also examined by H-1 NMR titration experiments.
