@misc{10481/93569, year = {2024}, month = {6}, url = {https://hdl.handle.net/10481/93569}, abstract = {Two novel Ce(III) metal organic frameworks (MOFs) with formulas [Ce(5Meip)(H-5Meip)]nGR-MOF-17 and [CeCl(5Meip)(DMF)]nGR-MOF-18 (5Meip = 5-methylisophthalate, DMF = N,N-dimethylformamide) have been synthesized, forming 3-dimensional frameworks. Magnetic measurements show that both compounds present field-induced slow magnetic relaxation under a small applied dc field. For GR-MOF-17, the temperature dependence of relaxation times is best described by a Raman mechanism, whereas for GR-MOF-18, relaxation occurs through a combination of Raman and local-mode pathways. Moreover, when avoiding short Ce⋯Ce interactions by magnetic dilution in GR-MOF-17@La and GR-MOF-18@La, only the local-mode mechanism is responsible for magnetic relaxation. Photophysical studies show the occurrence of ligand-centred luminescence in both compounds and phosphorescence emission at low temperature for GR-MOF-17.}, organization = {Gobierno Vasco/Eusko Jaurlaritza (IT1755-22, IT1500-22), Red Guipuzcoana de Ciencia, Tecnología e Innovación (FA385/2023, DG23/16)}, organization = {Junta de Andalucía (FQM-394, P21_00386 and ProyExcel_00386)}, organization = {SGIker of UPV/EHU and European funding (ERDF and ESF)}, organization = {Ministerio de Ciencia e Innovación for a Ramón y Cajal contract (the publication is part of the grant RYC2021-032522-I funded by MCIN/AEI/ 10.13039/501100011033 and the European Union “Next Generation-EU”/PRTR”)}, publisher = {Royal Society of Chemistry}, title = {Cerium(III) and 5-methylisophthalate-based MOFs with slow relaxation of magnetization and photoluminescence emission}, doi = {10.1039/d4dt00401a}, author = {Pajuelo Corral, Oier and Contreras, M.
