Synthesis and Properties of Highly Efficient Luminescent Zn-Tb and Zn-Eu Multimetal Complexes
Salen-type Schiff-base ligands (H2L) were synthesized through the condensation reaction between 1,2-diphenylethane-1,2-diamine and o-vanillin. Three novel luminescent Zn-Ln complexes, [ZnL]2Ln (Ln = Gd, Tb, Eu), were successfully prepared by reacting the zinc complex (ZnL) with LnCl3. Subsequent treatment of [ZnL]2Ln with dibenzoylmethane yielded three dinuclear derivatives, β-[ZnL]Ln (Ln = Gd, Tb, Eu). All complexes were comprehensively characterized by single-crystal X-ray diffraction and FT-IR spectroscopy. Structural analyses revealed that complexes 1–3 adopt trinuclear Zn-Ln-Zn architectures, whereas complexes 4–6 exhibit dinuclear Zn-Ln configurations. Solid-state photoluminescence measurements demonstrated quantum yields of 27.94% (ZnL), 0.90% ([ZnL]2Eu), 1.82% ([ZnL]2Tb), 1.05% ([ZnL]2Gd), 0.65% (β-[ZnL]Eu), 1.16% (β-[ZnL]Tb), and 0.70% (β-[ZnL]Gd), indicating their potential as advanced fluorescent rare-earth materials. The LED devices based on complexes β-[ZnL]Eu and β-[ZnL]Tb exhibit stronger emission intensities compared to those based on complexes [ZnL]2Eu and [ZnL]2Tb. The obtained complexes were fabricated in LED; the CIE chromaticity coordinates of complexes β-[ZnL]Eu and β-[ZnL]Tb are (0.344, 0.316) and (0.347, 0.323), respectively, which are very close to the standard white light coordinates (0.33, 0.33).
期刊介绍：
All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
