含双氨基硫脲支链结构荧光受体的合成及其阴离子识别研究

Fluorescent Receptor Containing Diaminothiourea Branches: Synthesis and Anion Recognition

合成了一种新的具有双氨基硫脲侧链结构的荧光阴离子受体2,6 二(萘硫脲基氨甲酰基)吡啶,通过核磁共振氢谱、质谱、红外光谱等进行了结构表征,并用荧光光谱滴定法测定了该阴离子受体与不同阴离子的络合选择性.结果表明,该阴离子受体对AcO-具有较高的选择性和荧光响应,对不同阴离子的络合选择性次序为:AcO->p NO2C6H4OPO2-4 Cl-.3,H2PO-

A novel fluorescent receptor was synthesized and characterized by ~1H NMR,MS,IR and Element Analysis. The binding properties for anions were studied by fluorescent titration method. The results show that the fluorescent receptor has a high selectivity and fluorescence responsibility to AcO^-. (It's) binding abilities to several anions follow the order: AcO^->p-NO_2C_6H_4OPO^(2-)_3,H_2PO^-_4Cl^-.
