Electro- and photochemical H-2 generation by Co(ii) polypyridyl-based catalysts bearing ortho-substituted pyridines

Rosario Scopelliti, Euro Solari, Albert Ruggi

Cobalt(II) complexes featuring hexadentate amino-pyridyl ligands have been recently discovered as highly active catalysts for the Hydrogen Evolution Reaction (HER), whose high performance arises from the possibility of assisting proton transfer processes v ...

Fluorinated Tetraarylethenes: Universal Tags for the Synthesis of Solid State Luminogens

Rosario Scopelliti, Kay Severin, Farzaneh Fadaei Tirani, Euro Solari, Abdusalom Suleymanov, Albert Ruggi

The aggregation-induced emission properties of tetraarylethenes (TAEs) have led to numerous applications in chemistry, biology, and materials science. Herein, we describe two fluorinated tetraarylethenes, which can be employed as universal tags for the syn ...

Acid-base-induced fac → mer isomerization of luminescent iridium(iii) complexes

Kay Severin, Farzaneh Fadaei Tirani, Albert Ruggi, Anastasia Gitlina

Luminescent Ir(C^N)3 complexes (C^N = cyclometalated arylpyridine ligand) exist in the form of two stable isomers with distinct photophysical and electrochemical properties: fac and mer. Herein, we show that fac-Ir(C^N)3 complexes can be converted into the ...

A ratiometric fluorescence sensor for caffeine

Laurane Favre, Kay Severin, Anne-Clémence Corminboeuf, Nicolas Luisier, Albert Ruggi, Nicolas David Gaeng

The dye disodium 3,4:3’,4’-bibenzo[b]thiophene-2,2’-disulfonate can be used as molecular probe for the fluorimetric detection of caffeine in aqueous solution. The fluorescence response is attributed to non-covalent interactions of caffeine with the dye in ...

Anthracene-Tethered Ruthenium(II) Arene Complexes as Tools To Visualize the Cellular Localization of Putative Organometallic Anticancer Compounds

Paul Joseph Dyson, Rosario Scopelliti, Christian Hartinger, Wee Han Ang, Alexey Nazarov, Olivier Pierre Zava, Michael Groessl, Albert Ruggi, Frédéric Schmitt, Julie Risse

Anthracene derivatives of ruthenium(II) arene compounds with 1,3,5-triaza-7-phosphatricyclo[3.3.1.1]decane (pta) or a sugar phosphite ligand, viz., 3,5,6-bicyclophosphite1,2-O-isopropylidene-alpha-D-glucofuranoside, were prepared in order to evaluate their ...

Synthesis of hyperbranched polyarylethenes by consecutive C–H vinylation reactions

Kay Severin, Albert Ruggi, Anastasia Gitlina

A novel procedure for the synthesis of polyarylethenes is described. Consecutive C–H vinylation reactions of tetraphenylethene with a triphenylethenyl triazene give hyperbranched polyarylethenes of variable sizes. The vinylation reactions are mediated by a ...

Synthesis of borasiloxane-based macrocycles by multicomponent condensation reactions in solution or in a ball mill

Rosario Scopelliti, Kay Severin, Albert Ruggi, Mirela Pascu

Large macrocycles containing imine and borasiloxane links are obtained in polycondensation reactions of 4-formylbenzeneboronic acid, t-Bu2Si(OH)2, and diamines. The multicomponent reactions can be performed in solution or – advantageously – by mechanochemi ...

Heptacoordinate Co-II Complex: A New Architecture for Photochemical Hydrogen Production

Euro Solari, Albert Ruggi

The first heptacoordinate cobalt catalyst for light-driven hydrogen production in water has been synthesized and characterized. Photochemical experiments using Ru(bpy)(3) as photosensitizer gave a turnover number (TON) of 16300molH(2)(molcat.)(-1) ac ...

Clathrochelate-based bipyridyl ligands of nanoscale dimensions: easy-to-access building blocks for supramolecular chemistry

Rosario Scopelliti, Kay Severin, Albert Ruggi, Matthew David Wise, Mirela Pascu

Boronic acid-capped clathrochelates were used to build rigid, linear bipyridyl ligands with adjustable lengths between 1.5 and 5.4 nm. The syntheses can be accomplished in one or two steps from simple starting materials. The potential of these ligands as b ...
