Abstract

The development of sensitive chemosensors capable of selective recognition of metal ions, especially for cations and anions with biological interest, has always been of particular significance, chemosensors find wide applications in many disciplines such as biochemistry, clinical and medical sciences, cell biology, analytical chemistry and environmental sciences. In this review, we first summarize the colorimetric and fluoroscence chemosensors for sensing of cations including transition metal cations and cations of s-block and p-block elements with the mechanism of analyte detection. The second part of this review highlights the chemosensors both colorimetric and fluoroscence for anion sensing. In this contest, special interest has been devoted to covers all the chemosensors for transition metal ions and cations of s & p-block elements and also the anions in a single review because in the literature, no report on the reviews covering the simultaneous detection of transition metal ions and cations of s & p-block elements and anions. In this contribution we review the chemical systems able to act as colorimetric and luminescent chemosensors for this class of metal cations and anions. This review also summarizes an important or biological as well as hazardous role played by these metal cations and anions in environment and human being. We hope, this review article is quite helpful for those researchers who are working in the field of sensors and switches for getting the brief introduction about sensors for metal cations and anions by referring this single review article.

Keywords: Photoinduced electron transfer, Electron energy transfer, Chemosensors, Transition metal ions, Ions of s & p-block elements and Anions.
