In order to explore the enantioselectivity of uranyl-salophens to chiral molecules, the newly designed receptors of Λ-type configuration sulfur/selenium-substituted uranyl-salophens with R/S-chiral δ-lactone were used to selectively coordinate and recognize a pair of enantiomers of RRS/SSR-3,5-dimethyl-2-(3-fluorophenyl)-2-morpholinols as guests based on the density functional theory calculations. The results indicated that the substituent effects of R/S-asymmetry sulfur/selenium-substituted uranyl-salophens significantly affected the structu...
