摘要:
利用荧光分析方法考察了荧光受体分子N-苯酰基-N-对硝基苯基硫脲与CH3COO-,HCO-3,H2PO-4 CO2-3,HSO-3,Br-,Cl-,SO2-4等阴离子的相互作用.结果显示该化合物对CO2-3具有较高的选择性识别能力,对不同阴离子的选择性从大到小依次为:CO2-3 ,HSO-3 , HCO-3 ,H2PO-4-, CH3COO- , Cl- , Br- , SO2-4.
Abstract:
The interactions of (N-p-nitrobenzolu-N-benzyoythiourea)thiourea with CH3COO-,HCO-3,H2PO-4, CO2-3, HSO-3, Br-, Cl-, SO2-4 were studied by fluorescence analysis. The results indicated that this new fluorescent receptor has a high selectivity and fluorescent responsibility to CO2-3 and its recognition ability for the anions appeared in the order of CO2-3, HSO-3, HCO-3, H2PO-4, CH3COO-, Cl-, Br-, SO2-4.
