Chiral fungicides R/S-metalaxyls(R/S-MTLs) and R/S-benalaxyls(R/S-BNLs) have different biotoxicity. It is very important to unravel molecular recognition and enantiomeric separation of R/S-MTLs or R/S-BNLs. In this paper, we designed a novel asymmetric ligand: 5-methoxy-2-(4-methoxy-6”-(quinazolin-2-yl)-[2,2”−bipyridin]-6-yl)quinazoline(MMQBQ), further constructed a new asymmetric receptor Uranyl-MMQBQ by coordination of MMQBQ with uranyl. The complexation and separation of receptor Uranyl-MMQBQ with guests R/S-MTLs or R/S-BNLs were systemat...
