    Three representative BINOL derivatives were examined for their chiral recognitions with d- and l-<i>t</i>-Boc-amino acid anions: an open system 1, which bears two urea groups and two pyrene groups; a closed ring system 2, which bears two urea groups with a closed ring system; and a dimeric system 3, which bears two benzylic amine groups and two pyrene groups. Dimeric system 3 displayed a Δ<i>I</i><sub>D</sub>/Δ<i>I</i><sub>L</sub> of 12.95 for <i>t</i>-Boc-alanine
