The public discussion of the master’s student (Hind Khalid Mustafa) from the Department of Chemistry - College of Science - University of Anbar was held on Tuesday, August 31, 2021 at Jaber Bin Hayyan Hall in the College of Science about her thesis tagged:

(( Coumarin derives: synthesis, characterization, mesomorphic behavior and thermal conduction))

It included the thesis submitted by the student (Hind Khalid Mustafa) from the Department of Chemistry to prepare two series of new derivatives Coumarin dimer based on liquid crystals were synthesized.  The structure of all the prepared liquid crystalline compounds were clarified by elemental microanalysis, CHN/O, FT-IR, 1H-NMR and 13C-NMR techniques. The liquid crystal properties (DSC) and (POM) and the measurement of the transition temperatures of the prepared compounds and related enthalpy values were studied through differential calorimetry (DSC) and the use of polarized light microscopy (POM) to study the quality of phases.The Photoluminescence (PL) of the  compounds was measured and the compounds emission photoluminescence in the visible region, the blue region, and the red region.The thermal conductivity of the prepared compounds was measured and the compounds were thermally conductive.
