Question

Propose the synthesis of a fluorescent polymer that has a thiourea attachted to potentially detected anion. Why might this compound be of interest to use as a sensor to detect anions?

Answer 1

Fluroscent is the phenominon in which the compound absorb light and which can emit radition with visible wavelength 400-800 nm wavelength and which shows fluroscence. The polymer in which the thiourea is attached is used to detector as a anions as fluroscent. In this the thiourea amine and sulphur atom forms hydrogen bonding with the metal anions.

anion sensors exploiting the thiourea motif capable of binding anions through hydrogen bonding interactions. The use of high resolution magic angle spinning 1H NMR allows the direct comparison of the anion binding properties of these receptors in solution versus those tethered to polymer resins.

by binding this metal anion with this thiourea polymer the absorption get increased and shows fluroscence.
