✦ Synopsis

Novel chromogenic 1,3-calix4 derivatives comprised of 1,1%-binaphthyl-, methyl-a-D-glucoside-and D-mannitol moieties in the crown ether ring have been synthesized. UV-vis spectroscopic measurements of the 2,4-dinitrophenylazo chromogenic molecules indicated noticeable chiral discrimination associated with coloration towards primary amine enantiomers.
