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

The crucial recognition events of chemistry, biology, and materials science occur in a much
smaller world than the one we are accustomed to. Information about these events can be …

Phosphate anions are one of the most important constituents of living systems. Together with
heterocyclic bases and sugars, phosphates make up DNA, the hereditary element of living …

Anion recognition chemistry has grown from its beginnings in the late 1960s with positively
charged ammonium cryptand receptors for halide binding to, at the end of the millennium, a …

According to one of Natures most fundamental laws, molecules may be differentiated by
having a positive, a negative, or no net charge at all. Although nothing may be known about …

Anions play essential rôles in biological processes; indeed, it is believed that they
participate in 70% of all enzymatic reactions. 1 There is, therefore, intense effort being …

The aromatic character of porphyrins, which has significant chemical and biological
consequences, can be substantially altered by judicious modifications of the parent ring …

The similarities and differences between the behavior of carbon-bound and terminal metal-
bound halogens and halide ions as potential hydrogen bond acceptors has been …

This review traces the emergence of pyrrole-based receptors for anion recognition. It
outlines how serendipitous findings that the diprotonated form of sapphyrin, a pentapyrrolic …
