Anionic Bipyridyl Ligands for Applications in Metallasupramolecular Chemistry

Rosario Scopelliti, Kay Severin, Mathieu Jérémie Marmier, Clément Schouwey, Mirela Pascu

The facile synthesis of anionic bipyridyl ligands with dinuclear clathrochelate cores is described. These metalloligands can be obtained in high yields by the reactions of M(ClO4)(2)(H2O)(6) (M: Zn, Mn, or Co) with 4-pyridylboronic acid and 2,6-diformyl-4- ...

ZrNO-Ag co-sputtered surfaces leading to E. coli inactivation under actinic light: Evidence for the oligodynamic effect

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi, Rosendo Sanjines, Mirela Pascu

This study reports visible light sensitive ZrNO and ZrNO-Ag polyester samples prepared by sputtering in an Ar/N-2/O-2 atmosphere leading to Escherichia coil bacterial inactivation. The bacterial inactivation by ZrNO avoids the increasing environmental conc ...

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 ...

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 ...
