Popis: | Chiral amphiphilic oxacalix[2]arene[2]triazine derivatives 1–3 bearing l-prolinol moieties were synthesized. The self-assembly behavior of the chiral macrocyclic amphiphiles was investigated. SEM, TEM, and DLS measurements demonstrated that 1 formed stable vesicles (size of ∼90 nm), whereas 2 and 3 formed micelles. As monitored by DLS, vesicles composed of 1 showed selective response to the chiral anions (2S, 3S)-2,3-dihydroxysuccinate (d-tartrate), S-mandelate and S-(+)-camphorsulfonate over their enantiomers. DFT calculations revealed that the enantioselectivity arises from cooperative anion-π interactions and hydrogen bonding between the chiral electron-deficient cavity and the organic anions. |
