High Brightness and Easy Color Modulation in Lanthanide-Based Coordination Polymers with 5-Methoxyisophthalate as Ligand: Toward Emission Colors Additive Strategy
Résumé
Reactions in water between lanthanide chlorides and the disodium salt of 5-methoxyisophthalic acid, Na2(mip)·7H2O, lead to the first three series of lanthanide-based coordination polymers based on this ligand. The first series contains only one compound with chemical formula [Ce(mip)3/2(H2O)5·2H2O]∞. The second series has general chemical formula [Ln(mip) (Hmip)(H2O)5·H2O]∞ with Ln = La–Ce. The last family is constituted by compounds with general chemical formula [Ln2(mip)3(H2O)8·4H2O]∞ with Ln = Sm–Er plus Y. Luminescent properties of the compounds that belong to this family have been studied. The Tb-based compound presents one of the brightest luminescences reported to date for a lanthanide-based coordination polymer. The weak intermetallic energy transfer evidenced on the third family of compounds allows easy and predictable color modulation of the heterobimetallic powders through additive colors strategy.
