Abstract

A bis-bisurea receptor (L) based on the R,R-cyclohexane-1,2-diamino scaffold forms an uncommon 2 : 2 complex (1) with the monohydrogen phosphate ion (HPO42−) and a 1 : 1 complex (2) with the sulfate ion (SO42−). Solution binding properties of the two anions were studied by 1H NMR, UV-vis, and circular dichroism (CD) methods.
