| 摘 要： | 为了探讨新型铀酰受体对丙硫磷的对映选择性,设计了一种新颖的配体:2-(2-羟基-3-甲氧基苯基)-9-(2-羟基苯基)硫代吡喃并3,2-h]硫代色烯-4,7-二酮(HTTDN),并将HTTDN与铀酰离子结合,来构建一个新的Uranyl-HTTDN受体。在本工作中,利用密度泛函理论研究了Uranyl-HTTDN对R/S-丙硫磷农药的对映选择性识别。结果表明,在真空和甲苯中,Uranyl-HTTDN可以通过与丙硫磷中的S3原子配位来有效的识别R/S-丙硫磷,选择性系数均大于90%。

| Abstract: | In order to explore the enantioselectivity of new uranyl receptor to prothiofos, a novel ligand was designed:2-(2-hydroxy-3-methoxyphenyl)-9-(2-hydroxyphenyl)thiopyrano3,2-h]thiochromene-4,7-dione(HTTDN), and then, HTTDN was bound to the uranyl ion to construct a new receptor of Uranyl-HTTDN. In this work, density functional theory (DFT) was used to study the enantioselective recognition of Uranyl-HTTDN to R/S-prothiofos (R/S-PTFs) pesticicdes. The result showed that in vacuum and toluene, Uranyl-HTTDN could effectively recognize R/S-prothiofos by coordinating with the S3 atom of prothiofos, and the selectivity coefficients were greater than 90%. |
