Divergent Synthesis of Densely Substituted Arenes and Pyridines via Cyclotrimerization Reactions of Alkynyl Triazenes

Kay Severin, Nicolai Cramer, Carl Thomas Bormann, Florian Gérald Abela, Jin Fay Tan, Frederick Mark Chadwick

Densely substituted fused aromatic triazenes can be prepared by [2 + 2 + 2] cyclotrimerization reactions of 1-alkynyl triazenes. The Cp*Ru-catalyzed cyclization proceeds well with both simple alkynyl triazenes and tethered 1-diynyl triazenes. Attractively, ...

Fine-tuning the coordination atoms of copper redox mediators: an effective strategy for boosting the photovoltage of dye-sensitized solar cells

Ulf Anders Hagfeldt, Chong Liu, Mei Wang

Natural systems have marvelously utilized copper complexes featuring sulfur-coordinating ligands, known as blue copper proteins, as efficient electron-transfer mediators in biological processes. Copper complexes with sulfur-coordinating ligands have been a ...

From structure to application: studies on adenine-, pyrene- and lanthanide-based metal-organic frameworks

Andrzej Gladysiak

Metal-organic frameworks (MOFs) are coordination polymer materials in which inorganic metal ions or clusters are linked with multitopic organic ligands by means of coordination bonds. Their structural versatility allows for design of materials based on pre ...

Biologically derived metal organic frameworks

Kyriakos Stylianou, Samantha Lynn Anderson

Metal organic frameworks (MOFs) are extended structures composed of a network of organic ligands and metal ions or clusters connected to each other via coordination bonds. The numerous choices of organic ligands and metal coordination geometries have led t ...

Fluorophores for Excited-State Intramolecular Proton Transfer by an Yttrium Triflate Catalyzed Reaction of Isocyanides with Thiocarboxylic Acids

Qian Wang, Jieping Zhu, Shuo Tong, Shun Zhao, Qing He

Discovery of new chemical reactivity of a given functional group can often result in innovative synthesis of important chemical entities that possess unprecedented properties. We designed and developed a one-step synthesis of 5-amino-4-carboxamidothiazoles ...

Highly selective immobilized bimetallic Ni-Au nanoparticle catalyst for the partial hydrogenation of m-dinitrobenzene

Paul Joseph Dyson, Lioubov Kiwi, Oliver Anthony Beswick, Fernando Cardenas Lizana, Daniel André Samuel Lamey

Transition metal nanoparticles (NPs) are extensively used as catalysts for a wide and diverse range of organic transformations when immobilized on appropriate solid supports. We describe the development of a highly active and highly selective heterogeneous ...

Complexation of [Gd(DTTA–Me)(H2O)2]− by Fluoride and Its Consequences to Water Exchange

Lothar Helm, Loïck Moriggi, Shima Karimi, Gail Ruth Hunter

The displacement of water molecule(s) from the inner coordination sphere of [Gd(DTTA–Me)(H2O)2]− (DTTA = ethylenetriamine-N,N,N″,N″-tetraacetate) by fluoride has been studied by multinuclear NMR relaxation (1H, 17O, 19F) and DFT calculations. Fluoride anio ...

Hg(II) coordination complexes containing the tris(2-pyridylmethyl) amine ligand: Synthesis, characterization and crystal structure analysis

Kurt Schenk, Farzaneh Fadaei Tirani

Two new Hg(II) coordination compounds containing the tris(2-pyridylmethyl)amine (TPA) ligand were synthesized by conventional and sonochemical methods, characterized by spectroscopic techniques (FT-IR and elemental analysis) and their X-ray crystallographi ...

Water exchange studies of lanthanide complexes and aqua ions

Shima Karimi

Complexes of lanthanide (III) ions have been used in structural studies of biomolecules and as contrast agents (CA). Clinically approved CAs have only one water molecule in their first coordination sphere. Structure and water exchange rate of these complex ...
