Preparation and Characterization of Stable Molecular Glasses of Europium(III) Acyl-Alaninate Complexes

Abstract:

Working with acylaminocarboxylate ligands, we used ethanol and water as a solvent, and the europium complexes were prepared using a chemical reaction method in solution. The elements were analyzed and characterized by polarizing microscope and XRD, respectively. The surfaces of complexes in the solid state were observed by polarizing microscope morphology. XRD diffraction data confirms the periodic long range order/disorder structure of these europium complexes. We also found that diversified material was easily formed by the rare earth complexes. Using the above tests, the structural information of the Eu complexes in the glassy state, liquid crystal glassy state and crystalline states was obtained
