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 ...

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

Rosario Scopelliti, Euro Solari, Albert Ruggi, Vincent Artero, Fiorella Lucarini

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 ...

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

Kay Severin, Albert Ruggi, Farzaneh Fadaei Tirani, Carolina Luciana Plaice, 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 ...

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

Kay Severin, Rosario Scopelliti, Euro Solari, Albert Ruggi, Farzaneh Fadaei Tirani, Abdusalom Suleymanov, Thibault Jacques Marie Damiens Vanrapenbusch, Barbara Maja Kraus

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 ...

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

Euro Solari, Albert Ruggi, Serhii Vasylevskyi, Fiorella Lucarini

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

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

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 ...

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

Kay Severin, Rosario Scopelliti, Mirela Pascu, Albert Ruggi

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 ...

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

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

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 ...

A ratiometric fluorescence sensor for caffeine

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

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 ...
