Schematic representation of the dynamic process of interconversion between the two conformers of the Pd complex in CDCl3 solution.
An intense research is going on all over the world to develop effective and selective receptors for anions in aqueous solution. We developed a series of novel pyrrole-based acyclic, cyclic and bicyclic receptors. Some of these receptors are shown to be selective for sulfate ion in aqueous/organic medium and fluoride ion in DMSO in the presence of other competing anions.
