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 …

Calix [n] arenes (n= 4, 5, 6, 8) are “chalicelike” phenol-based macrocycles that are among
the most fascinating and highly studied scaffolds in supramolecular chemistry. This stems …

This critical review focuses on the development of anion sensors, being either fluorescent
and/or colorimetric, based on the use of the 1, 8-naphthalimide structure; a highly versatile …

In the past few decades, the development of chemosensors has become an important
research topic in supramolecular analytical chemistry, and as a result, it has attracted the …

This review article focuses primarily on the work carried in our laboratories over the last few
years using luminescent and colorimetric sensors, where the anion recognition occurs …

Since 1992 a variety of urea-based anion receptors have been synthesised, of varying
complexity and sophistication. This critical review will focus on some distinctive aspects of …

This critical review includes advances in anion complexation in the year 2007. The review
covers anion receptors that employ amides and thioamides, pyrroles and indoles, ureas and …

This critical review covers advances in anion complexation chemistry related to receptors
based on organic frameworks in the years 2005–2006. The review covers anion receptors …

1, 3-bis (4-nitrophenyl) urea (1) interacts through hydrogen bonding with a variety of
oxoanions in an MeCN solution to give bright yellow 1: 1 complexes, whose stability …

This critical review highlights recent advances in the structurally modified (thio) urea-based
receptors for anion complexation and sensing. Modifications of the (thio) urea structure are …
