Abstract

The synthesis, structure, and anion binding properties of chromogenic octamethylcalix [4] pyrroles (OMCPs) and their N-confused octamethylcalix [4] pyrrole isomers (NC-OMCPs) containing an inverted pyrrole ring connected via α'-and β-positions are described. X-ray diffraction analyses proved the structures of two synthesized isomeric pairs of OMCPs and NC-OMCPs. The addition of anions to solutions of chromogenic OMCPs and NC-OMCPs ...
