A smart low molecular weight gelator for the triple detection of copper (II), mercury (II), and cyanide ions in water resources

Rosario Scopelliti

Novel supramolecular gelators based on quinoline-indolin-2-one structure were synthesized. These gelators formed stable organogels in a mixture of DMSO/H2O (1:1). The scanning electron microscopy (SEM), IR and NMR spectroscopies, and rheological measuremen ...

Cu Photoredox Catalysts Supported by a 4,6-Disubstituted 2,2 '-Bipyridine Ligand: Application in Chlorotrifluoromethylation of Alkenes

Xile Hu, Murat Alkan

Interest in base metal catalysis motivates the development of Cu-based photoredox catalysts for organic synthesis. However, only a few Cu catalysts have been applied in photoredox reactions, the majority of which contain one or two 1,10-phenanthroline liga ...

Dinuclear clathrochelate complexes with pendent cyano groups as metalloligands

Rosario Scopelliti, Kay Severin, Henrik Moodysson Rønnow, Philip Pattison, Ivica Zivkovic, Bálint Náfrádi, Euro Solari, Giacomo Cecot, Mathieu Jérémie Marmier, José Luis Bila

Dinuclear clathrochelate complexes with two, three, four, or five cyano groups in the ligand periphery were prepared following two distinct synthetic strategies: (a) zinc(II)- or cobalt(II)-templated polycondensation reactions of CN-functionalized arylboro ...

Acid-Induced Degradation of Phosphorescent Dopants for OLEDs and Its Application to the Synthesis of Tris-heteroleptic Iridium(III) Bis-cyclometalated Complexes

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Julien Edouard Frey

Investigations of blue phosphorescent organic light emitting diodes (OLEDs) based on [Ir(2-(2,4-difluorophenyl)pyridine)(2)(picolinate)] (FIrPic) have pointed to the cleavage of the picolinate as a possible reason for device instability. We reproduced the ...

A bright tetranuclear iridium(III) complex

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Davide Di Censo

A cyclic tetranuclear cyclometallated iridium(III) complex using cyanide anions as bridging ligands and displaying a tetrahedrally distorted square geometry has been obtained with high yield; photo- and electrochemical characterizations show that most inte ...

N-Aryl Chromophore Ligands for Bright Europium Luminescence

Rosario Scopelliti, Jean-Claude Bünzli, Svetlana Eliseeva

Sterically hindered N-aryl-benzimidazole pyridine-2-carboxylic acids (aryl = phenyl, 4-biphenyl, 2-naphthyl) readily form homoleptic, neutral, nine-coordinate europium complexes which display efficient sensitized luminescence in solid state and in dichloro ...

Nickel Complexes of a Pincer Amidobis(amine) Ligand: Synthesis, Structure, and Activity in Stoichiometric and Catalytic C—C Bond Forming Reactions of Alkyl Halides

Rosario Scopelliti, Xile Hu, Oleg Vechorkin

NiII complexes of the new pincer amidobis(amine) ligand are described. The Ni chloride complex catalyzes Kumada-Corriu-Tamao coupling of unactivated alkyl halides with alkyl Grignard reagents, as well as double C-C coupling of CH2Cl2 with alkyl Grignard re ...
