Chemical Sensors: Main Group Compounds for Anion Detection

Papers on sensing of anions by main group element compounds, which were published in the last decade, are reviewed. Most of them concern fluoride sensing utilizing functionalized triarylboranes. Introduction of an electron-withdrawing group such as a cationic group, chelate formation, and formation of hydrogen bonding are very useful to improve the complexation ability of sensors with anion. Color change of absorption and emission, on-off of fluorescence and phosphorescence, and change of redox potential are mainly used as a signal for anion sensing. Sensing of adenosine diphosphate and adenosine triphosphate, which are very important anions in life science, is also presented.
