Enantioselective nanofiber-spinning of chiral calixarene receptor with guest†
Abstract
Chiral para-tert-butylcalix[4]arene bearing (S)-α-methylbenzylamine groups at lower rim only self-assembles with one of two enantiomers of 2,3-dibenzoyltartaric acid into coiled nanofibers and the coiled nanofibers only stack with the nanofibers having the same handedness to construct bigger ribbon-like fibers bearing porosity.
