The study of the complexation of anions, from its beginnings in the late 1960s and 1970s,(1-
3) has moved on from being an area solely of academic interest to a fundamental pillar of …

Sensing of metal ions and anions is of great importance because of their widespread
distribution in environmental systems and biological processes. Colorimetric and fluorescent …

Calix [4] pyrrole and its derivatives are key members of the supramolecular Parthenon along
with other well-recognized receptor systems, such as crown ethers, cyclodextrins (CDs) …

A calix [4] pyrrole-decorated pillar [5] arene was synthesized via azide-alkyne “click”
chemistry and used to prepare a cross-linked supramolecular polymer in chloroform based …

We report on the synthesis of a new receptor for anions, meso-substituted hexapyrrolic calix
[4] pyrrole 1. The calix [4] pyrrole's core features two additional pyrrole side-arms suspended …

An AB2‐type monomer comprised of a calix [4] pyrrole skeleton and alternating bis‐
carboxylate units is reported and used for the construction of a novel supramolecular …

Highly stereoselective synthesis of 3-pyrrole substituted β-lactams is accomplished. The first
step involves the synthesis of 3-phthalimido substituted β-lactams following Staudinger …

Four novel deeply coloured and highly fluorescent anion sensors have been developed by
coupling calix [4] pyrrole with two different diketopyrrolopyrroles. The sensors showed both …

Liquid–Liquid Extraction (LLE) is a venerable and widely used method for the separation of
a targeted solute between two immiscible liquids. In recent years, this method has gained …

Four new calix [4] pyrroles with the shortest possible strap so far through ortho-linking of the
aromatic unit have been synthesized, including a naphthalene-derived fluorescent receptor …
