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 …

This Tutorial Review provides a short survey of anion sensing by small molecule anion
receptors, molecular ensembles and chemodosimeters. The review highlights the many …

Chemodosimeters–the reaction based sensing systems for F− ions provide the significantly
higher selectivity due to specificity of their reactions and also better opportunities for analysis …

The incorporation of aryl substituents at the meso-positions of calix [4] pyrrole (C4P)
scaffolds produces aryl-extended (AE) and super-aryl-extended (SAE) calix [4] pyrroles. The …

A sunlight induced simple green route has been developed for the synthesis of polyacrylate
functionalized gold nanoparticles (PAA-AuNPs), in which poly (acrylic acid) functions as a …

Calix [4] pyrroles and their congeners are conformationally flexible, nonplanar tetrapyrrolic
macrocycles that can recognize anionic substrates. Although the mother calix [4] pyrrole was …

Calixarenes are considered as third generation supramolecules with hollow cavity-like
architecture whereas nanoparticles are small entities with dimensions in the nanoscale …

Calix [4] pyrroles are an important class of oligopyrrolic macrocycles and have found
applications in many diverse fields including anion recognition. To modulate the properties …

To prepare new functional covalent architectures that are difficult to synthesize using
conventional organic methods, we developed a strategy that employs metal–organic …
