Meso-diacylated calix[4]pyrrole: Atructural diversities and enhanced binding towards dihydrogenphosphate ion

Abstract

Meso-diacylated calix[4]pyrrole was obtained via acid catalysed condensation of meso-acylated dipyrromethane with acetone. Selective presence of flexible substituents at the calix[4]pyrrole periphery led to interesting structural motifs in the solid state along with enhanced binding towards anions, especially dihydrogenphosphate ion via anchoring. © 2011 The Royal Society of Chemistry.
