planar Pt(II) complexes as luminescent biosensors for DNA detection in solution. The sensing is attributed to the aggregation induced bright red photoluminescence (AIPE) of the complexes in the presence of DNA that can be seen with the naked eye using only a 360 nm light source. Terpyridine appended luminescent geminal bistriazoles (L1–L4, from geminal bisazide A through azide–alkyne ‘click’ cycloaddition)
我们报告了方形平面 Pt( II ) 配合物作为用于溶液中 DNA 检测的发光生物传感器。传感归因于在仅使用 360 nm 光源的情况下可以用肉眼看到的 DNA 存在下复合物的聚集诱导的亮红色光致发光 (AIPE)。探索了具有多种螯合位点的三联吡啶附加的发光偕双三唑(L1-L4,从偕二叠氮化物 A 到叠氮化物-炔烃“点击”环加成)与 Pt(dmso) 2 Cl 2 的金属配位和反应,产生 Pt( II ) 具有不同的 N∩N 配体环境。热稳定宝石-双叠氮化物和双三唑在文献中几乎没有报道,这是三联吡啶附加的双叠氮化物和双三唑的首次报道。

data, density functional calculations, and electron spectroscopy. The structure of the complex of 4′-(4-methylsulfanyl)-2,2′:6′,2"-terpyridine with Ni(BF4)2 was also established by X-ray diffraction analysis. A method was proposed for the preparation of gold nanoparticle dimeric aggregates via coordination interactions of the ligands adsorbed on the gold nanoparticle surface with transition metal ions
Synthesis, Characterization, Photophysical, and Anion-Binding Studies of Luminescent Heteroleptic Bis-Tridentate Ruthenium(II) Complexes Based on 2,6-Bis(Benzimidazole-2-yl)Pyridine and 4′-Substituted 2,2′:6′,2′′ Terpyridine Derivatives
compounds were designed to increase the excited-state lifetime of ruthenium(II) bisterpyridine-type complexes. The X-ray crystal structure of a representative compound 2, which crystallized with monoclinic space group P2(1)/c, has been determined. The absorption spectra, redox behavior, and luminescence properties of the ruthenium(II) complexes have been thoroughly investigated. All of the complexes display
