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 Al(3+) 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 (Φ) measurements, BFQ-Zn(2+), BFQ-Al(3+) and BFQ-F(-) complexes showed 16, 22 and 30 times higher Φ values than BFQ, respectively. The complexation properties of BFQ with Zn(2+), Al(3+) and F(-) ions were also examined by (1)H NMR titration experiments.
一种基于双酚A - 喹啉共轭物(BFQ)的新型多分析物荧光传感器通过两个简便步骤合成并进行了系统表征。在乙醇 - 水(体积比v/v = 9/1)中,BFQ对Zn(2+)和Al(3+)阳离子表现出有效选择性和灵敏识别,相对于其他阳离子具有显著增强的荧光强度;在乙腈中,BFQ对F(-)阴离子相对于其他阴离子也有类似表现。根据量子产率(Φ)测量,BFQ - Zn(2+)、BFQ - Al(3+)和BFQ - F(-)配合物的Φ值分别比BFQ高16倍、22倍和30倍。还通过(1)H NMR滴定实验研究了BFQ与Zn(2+)、Al(3+)和F(-)离子的络合性质。
