Translated title:
Synthesis, Characterisation and Properties of New Metal-Organic frameworks
Summary:
The present PhD thesis focuses on the synthesis of new Metal-Organic Frameworks (MOFs), their characterisation and the study of their properties towards an effective application in two demanding research fields; sorption of metal ions from water and emission of white light.
The synthesis of the presented MOFs is based on two organic linkers of oxalamide nature; N,N’-bis(2-carboxyphenyl)-oxalamide and N,N’-bis(2,4-dicarboxyphenyl)-oxalamide with the second ligand being a newly synthesised and published ligand by our research group. In total, twenty one new coordination polymers (CP) were synthesised, two one-dimensional (1D), ten two-dimensional (2D) and nine three-dimensional (3D). The crystal structures of all of the CPs are described and a variety of topologies are demonstrated, with three of the 3D MOFs exhibiting a new topology.
Of the twenty one new compounds introduced herein, a 2D calcium based coordination polymer (Ca-MOF) was found able to exchange the Ca2+ ions by Cu2+ rapidly and almost quantitatively. This discovery led to extensive batch ion-exchange studies along with the exploitation of Ca-MOF as a stationary phase in an ion-exchange column for Cu2+ removal from aqueous media. Moving a step forward, after having established Ca-MOF’s sorption ability regarding the Cu2+ ion, the possibility of exchanging Ca2+ with lanthanide ions was explored. Aiming at the emission of white light, the Ca-MOF exchanged Ca2+ with Eu3+ and Tb3+ at various ratios resulting in materials that combine blue, red and green emission to finally yield white light.
