azide-functionalized rutheniumcomplexes were synthesized. Six trisbipyridine rutheniumcomplexes bearing one to six azide functions were developed from the corresponding carboxy derivatives. By using four alkyne-functionalized DNA sequences and performing copper-catalyzed azide–alkyne cycloaddition (CuAAC) clickchemistry reactions, the formation of symmetric and unsymmetric multivalent DNA–ruthenium conjugates was
合成了一系列新的叠氮化物功能化钌配合物。从相应的羧基衍生物开发了六个带有一到六个叠氮化物功能的三联吡啶钌配合物。通过使用四个炔烃功能化的 DNA 序列并进行铜催化的叠氮化物-炔烃环加成 (CuAAC) 点击化学反应,实现了对称和不对称多价 DNA-钌共轭物的形成。它们由一到六个寡核苷酸组成。
Syntheses, characterization, and photo-hydrogen-evolving properties of tris(2,2′-bipyridine)ruthenium(<scp>ii</scp>) derivatives tethered to a cis-Pt(<scp>ii</scp>)Cl<sub>2</sub>unit: insights into the structure–activity relationship

In the present study, an attempt has been made to utilize a Ru(ii)-complex-sensitized ZnO hybrid along with a Pt(ii) salt for the visible light aided photoreduction of 4-nitrophenol.
width of a single molecule of the hydrogelator. These results illustrate that metal complexes, besides being able to impart rich optical, electronic, redox, or magnetic properties to supramolecular hydrogels, also offer a unique geometrical control to prearrange the self-assembly motif prior to self-assembling. The use of metal complexes to modulate the dimensionality of intermolecular interactions may

The synthesis and anion‐recognition properties of the first halogen‐bonding rotaxane host to senseanions in water is described. The rotaxane features a halogen‐bonding axle component, which is stoppered with water‐solubilizing permethylated β‐cyclodextrin motifs, and a luminescent tris(bipyridine)ruthenium(II)‐based macrocycle component. 1H NMR anion‐binding titrations in D2O reveal the halogen‐bonding
描述了第一个用于感知水中阴离子的卤素键合轮烷主体的合成和阴离子识别特性。该轮烷具有卤素键合轴成分,该成分由水溶性全甲基化β-环糊精基序封端,以及发光的三(联吡啶)钌(II)基大环成分。D 2 O 中的1 H NMR 阴离子结合滴定揭示了卤素键合轮烷以高亲和力和选择性地结合较小的卤化物阴离子和硫酸根。通过分子动力学模拟和自由能计算解释了结合亲和力趋势。光物理研究表明,通过增强大环组分的 Ru II金属配体电荷转移 (MLCT) 发射,互锁卤素键主体能够感知水中的碘化物。
