ITACONIC ACID BASED COORDINATION POLYMER: MECHANOCHEMICAL SYNTHESIS, CHARACTERIZATION AND VAPOCHROMIC STUDY

Abstract

Itaconic acid based coordination polymer (CP) was synthesized through a mechanochemical reaction between itaconic acid ligand and copper (II) salt. The [Cu(Itac)2] CP was characterized by elemental analysis, Infrared spectroscopy, UV-Visible spectrophotometry and powder x-ray diffractometric analysis which confirmed its synthesis. In the application of [Cu(Itac)2], vapochromic behavior was carried out with different solvents vapour. Result revealed methanol having the highest sorption values of 1.44 moles. Also, the adsorption of the solvents vapour on [Cu(Itac)2] increased in the order of methanol > DMF > ethanol > acetone > isopropanol > benzene > toluene. The polarity of the solvents, solvent sizes and the unique affinity of [Cu(Itac)2] CP to some solvents may account for trend observed in rate of solvents uptake. These results indicate that [Cu(Itac)2] could be used to remove unwanted solvent vapour from contaminated air due to their reasonably large surface area.
