In this work, we present the synthesis, solid state characterization and complete photoluminescence study of new important homobimetallic lanthanide complexes containing the non-steroidal anti-inflammatory drug (NSAID) naproxen. The anal. and spectroscopic techniques reveals the formation of eight compounds of general formula [Ln2(nap)6(H2O)4] (Eu 1 and Gd 2), [Ln2(nap)6(bpy)2] (Eu 3 and Gd 4), [Ln2(nap)6(4,4′-dmbpy)2] (Eu 5 and Gd 6) and [Ln2(nap)6(phen)2] (Eu 7 and Gd 8), where: nap = naproxen ligand, bpy =2,2′-bipyridine, 4,4′-dmbpy = 4,4′-dimethyl-2,2′-bipyridine and phen = 1,10-phenanthroline. Using the RM1 model, the mol. structures of the EuIII complexes were calculated, with your optimized ground state geometries used to obtain all details involved in the energy transfer process. From the resp. GdIII complexes were obtained the lowest ligand triplet states, proving that the photoluminescence in the EuIII naproxen complexes is proposed to be a ligand sensitized luminescence process. On the other hand, the position of the triplet states also explains the non-effective energy transfer in the TbIII naproxen complexes. The presence of N,N-donors ligands (bpy, 4,4′-dmbpy and phen) results in an 3-4-fold increase in the quantum efficiency when compared with the EuIII complex without nitrogen ligands. The high values of emission quantum efficiency (η ∼ 70 – 98%) show the EuIII complexes can be potential candidates as emitters in biol. assays. After reading the article, we found that the author used 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Application of 1134-35-6)
4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6) is used as a chemical Intermediate. It can be used for the determination of ferrous and cyanide compounds.Application of 1134-35-6 Furthermore, 4,4′-Dimethyl-2,2′-bipyridine is used in the synthesis of a series of o-phenanthroline-substituted ruthenium(II) complexes.
