Crystal Structure and Photoluminescence of Two Terbium Compounds with Bromobenzoic Acid and Phenanthroline.
Two novel Tb(III) ternary complexes, [Tb2(Phen)2(p-BrBA)6] and [TbY(Phen)2(p-BrBA)6], have been synthesized with p-bromobenzoic acid(p-BrBA) as the primary ligand and 1,10-phenanthroline(Phen) as the secondary ligand. The structures of these complexes are characterized by elemental analysis, IR spectroscopy, UV-vis absorption spectroscopy, thermal analysis (TGA) and single-crystal X-ray diffraction. The crystal structures of the compounds are similar because of similar radii of Tb3+ ion and Y3+ ion. Both the homobimetallic single crystal and the heterobimetallic single crystal belong to the monoclinic system. The results show that both complexes have excellent luminescence properties, including luminescent intensity, luminescent lifetime and quantum yield. The two compounds have an excited state lifetime of milliseconds and the photoluminescence quantum efficiencies of the two terbium complexes can exceed 100% upon excitation to their 5d states in theory, which is attributed to luminescent lifetime and quantum cutting (QC). Furthermore, the luminescent properties of [TbY(Phen)2(p-BrBA)6] are actually superior to those of [Tb2(Phen)2(p-BrBA)6].
期刊介绍：
Journal of Fluorescence is an international forum for the publication of peer-reviewed original articles that advance the practice of this established spectroscopic technique. Topics covered include advances in theory/and or data analysis, studies of the photophysics of aromatic molecules, solvent, and environmental effects, development of stationary or time-resolved measurements, advances in fluorescence microscopy, imaging, photobleaching/recovery measurements, and/or phosphorescence for studies of cell biology, chemical biology and the advanced uses of fluorescence in flow cytometry/analysis, immunology, high throughput screening/drug discovery, DNA sequencing/arrays, genomics and proteomics. Typical applications might include studies of macromolecular dynamics and conformation, intracellular chemistry, and gene expression. The journal also publishes papers that describe the synthesis and characterization of new fluorophores, particularly those displaying unique sensitivities and/or optical properties. In addition to original articles, the Journal also publishes reviews, rapid communications, short communications, letters to the editor, topical news articles, and technical and design notes.
