Abstract

Based on [Ln(L)3(H2O)2] (Ln = Nd, Yb or Er) complexes self-assembled from a trifluorinated acylpyrazole-type β-diketonate ligand HL ((Z)-3-methyl-1-phenyl-4-(2,2,2-trifluoro-1-hydroxyethylidene)-1H-pyrazol-5(4H)-one) and LnCl3·6H2O, a series of NIR luminescent PMMA-supported hybrid materials PMMA@[Ln(L)3(H2O)2] are obtained from physical doping. The immobilization of the luminescent species via physical and chemical interactions within the polymeric PMMA matrix also acting as co-sensitizer, endows the enhanced NIR luminescent properties (Φem= 0.85-0.97%) in comparison to the individual Ln3 +-β-diketonate complex (Φem= 0.53-0.79%) besides the improved thermal-stability properties.
