Because of the significant roles played by metal ions in biological system, colorimetric sensing of transition metal by synthetic receptors is of considerable interest. In particular, cobalt is a rare heavy metal playing an essential role in ruminant nutrition. It is also a key element in vitamin B12. During this work, a simple dipodal Schiff's base has been synthesized and studied for sensing of transition metal ions, displaying visible color chnage in water. This presentation will focus the synthesis, characterization and solution binding studies of this receptor for transition metal ions.
