Facile synthesis and characterization of macromolecular Eu(III) complexes with beta-diketone ligands and poly(4-vinyl pyridine-co-methyl methacrylate)
Poly(4-vinyl pyridine-co-methyl methacrylate), PVM, was synthesized by radical copolymerization of 4-vinyl pyridine with methyl methacrylate. Afterward, the macromolecular Eu(III) complexes of general formula [Eu(beta-diketonate)(3)(PVM)(H2O)], where beta-diketonate = benzoylacetonate (BA),1; dibenzoylmethanate (DBM),2; thenoyltrifluoroacetonate (TTA),3, were prepared and fully characterized by means of element analysis, thermal analysis, SEM,H-1 NMR,C-13 NMR, FT-IR, and UV-vis spectra. The macromolecular complexes can dissolve in many ordinary organic solvents (e.g. dimethylformamide, dimethylsulfoxide, and tetrahydrofuran), as well as emit strong red luminescence under ultraviolet light excitation. The room-temperature(5)D(0)lifetime and fluorescence quantum yield of3are 391 mu s and 37%, respectively, which are far more than those of1(194 mu s, 16%),2(160 mu s, 18%), and Eu(TTA)(3)(H2O)(2)(224 mu s, 22%). The CIE coordinates of1-3are calculated as (0.49, 0.33), (0.62, 0.33) and (0.65, 0.34), respectively, demonstrating the promising utilization future of these complexes, especially the latter two, as luminescent functional materials used in large-area optical display.
