Highly luminescent charge-neutral europium(iii) and terbium(iii) complexes with tridentate nitrogen ligands.
We report on the synthesis of tridentate-nitrogen pyrazole-pyridine-tetrazole (L(1)H) and pyrazole-pyridine-triazole (L(2)H) ligands and their complexation with lanthanides (Ln = Gd(iii), Eu(iii) and Tb(iii)) resulting in stable, charge-neutral complexes Ln(L(1))3 and Ln(L(2))3, respectively. X-ray crystallographic analysis of the complexes with L(1) ligands revealed tricapped trigonal coordina...
متن کاملEuropium (III) Organic Complexes in Porous Boron Nitride Microfibers: Efficient Hybrid Luminescent Material
We report the design and synthesis of a novel kind of organic-inorganic hybrid material via the incorporation of europium (III) β-diketonate complexes (Eu(TTA)3, TTA = 2-thenoyltrifluoroacetone) into one-dimensional (1D) porous boron nitride (BN) microfibers. The developed Eu(TTA)3@BN hybrid composites with typical 1D fibrous morphology exhibit bright visible red-light emission on UV illuminati...
متن کاملDesign of Novel, Water Soluble and Highly Luminescent Europium Labels with Potential to Enhance Immunoassay Sensitivities.
To meet the continual demands of more-sensitive immunoassays, the synthesis of novel luminescent Eu(III) chelate labels having similar substituted 4-(phenylethynyl)pyridine chromophores in three different chelate structure classes are reported. Significantly enhanced luminescence intensities were obtained, evidently caused by the intra-ligand charge transfer (ILCT) mediated sensitization, but t...
متن کاملPhotostability of a highly luminescent europium beta-diketonate complex in imidazolium ionic liquids.
A high quantum yield and an enhanced photostability was found for a europium(III) tetrakis(2-thenoyltrifluoroacetonate) complex after dissolving the complex in a weakly-coordinating imidazolium ionic liquid.
متن کاملDitopic bis-terdentate cyclometallating ligands and their highly luminescent dinuclear iridium(III) complexes.
A new family of bridged cyclometallating ligands is reported, which incorporate two terdentate N(∧)C(∧)N-coordinating binding sites linked via pyrazine, pyrimidine or pyridazine units. Dinuclear Ir(III) complexes of one ligand have been prepared and crystallographically characterised; they display intense red phosphorescence.
