Engineering polymers with improved charge transport properties from bithiophene-containing polyamides

John Christopher Plummer, Rosario Scopelliti, Holger Frauenrath, Farzaneh Fadaei Tirani, Bilal Özen, Nicolas Candau

Polymer semiconductors show unique combinations of mechanical and optoelectronic properties that strongly depend on their microstructure and morphology. Here, we have used a model pi-conjugated bithiophene repeat unit to incorporate optoelectronic function ...

Low‐Temperature Intramolecular [4+2] Cycloaddition of Allenes with Arenes for the Synthesis of Diene Ligands

Rosario Scopelliti, Matthew Wodrich, Jérôme Waser, Farzaneh Fadaei Tirani, Durga Prasada Rao Hari, Guillaume Dominique Pisella, Artem Tsymbal

The intramolecular [4+2] cycloaddition between arenes and allenes first reported by Himbert gives rapid access to rigid polycyclic scaffolds. Herein, we report a one‐pot oxyalkynylation/cycloaddition reaction proceeding under mild conditions (23–90 °C) and ...

Crystallization and Organic Field-Effect Transistor Performance of a Hydrogen-Bonded Quaterthiophene

Philippe Bugnon, Rosario Scopelliti, Stéphane Suarez, Anne-Clémence Corminboeuf, Holger Frauenrath, Jan Gebers, Riccardo Petraglia, Piotr De Silva, Bilal Özen

Crystalline thin films of pi-conjugated molecules are relevant as the active layers in organic electronic devices. Therefore, materials with enhanced control over the supramolecular arrangement, crystallinity, and thin-film morphology are desirable. Herein ...

Hexayne Amphiphiles and Bolaamphiphiles

Rosario Scopelliti, Holger Frauenrath, Enzo Jean Raymond Bomal, Vincent Matthieu Guillaume Croué, Reuben Yeo Jueyuan

Oligoynes with two or more conjugated carbon-carbon triple bonds are useful precursors for carbon-rich nanomaterials. However, their range of app0lications has so far been severly limited by the challenging syntheses, particularly in the case of oligoynes ...

Liquid State and Zombie Dye Sensitized Solar Cells with Copper Bipyridine Complexes Functionalized with Alkoxy Groups

Michael Graetzel, Jacques-Edouard Moser, Shaik Mohammed Zakeeruddin, Joël Teuscher, Rosario Scopelliti, Ulf Anders Hagfeldt, Marko Stojanovic, Yasemin Saygili, Marina Freitag, Hui-Seon Kim

Copper redox mediators can be employed in dye sensitized solar cells (DSCs) both as liquid electrolytes or as solid state hole transport materials (HTMs). The solid state devices that employ copper complex HTMs can be simply obtained by solvent evaporation ...

SET processes in Lewis acid–base reactions: the tritylation of N-heterocyclic carbenes

Andrzej Sienkiewicz, Kay Severin, Rosario Scopelliti, Cristian Pezzato, Farzaneh Fadaei Tirani, Zhaowen Dong

Reactions between N-heterocyclic carbenes (NHCs) and the trityl cation, [Ph3C]+, give covalent adducts of type [NHC–CPh3]+ and/or [NHC–C6H5–CPh2]+. EPR spectroscopy, UV-Vis analyses, and trapping experiments imply that adduct formation involves carbene rad ...

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 ...

Assembly of High-Spin [Fe-3] Clusters by Ligand-Based Multielectron Reduction

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Davide Toniolo

The hexanuclear [Na12Fe6(tris-cyclo-salophen)(2)(THF)(14)], 1-THF, and the trinuclear [Na6Fe3(tris-cyclo-salophen)(py)(9)], 1-py, Fe(II) clusters can be easily assembled in one step from the ligand-based reduction of the [FeII(salophen)(THF)] complex. Thes ...

Two-Step Synthesis of Linear and Bent Dicarboxylic Acid Metalloligands with Lengths of up to 3 nm

Kay Severin, Rosario Scopelliti, Farzaneh Fadaei Tirani, Suzanne Maria Jansze, Ophélie Marie Planes

Nanometer-sized polycarboxylate ligands are interesting building blocks for metallasupramolecular chemistry, but access to these compounds is often limited by complicated synthetic pathways. Here, we describe a simple two-step protocol, which allows prepar ...

Boronate Ester-Capped Helicates

Kay Severin, Rosario Scopelliti, Daniel Ortiz Trujillo, Farzaneh Fadaei Tirani, Adrien Bryan Depallens, Erica Giraldi

Triple‐stranded helicates were obtained by metal‐templated multicomponent reactions of bispyridyloxime ligands with arylboronic acids. The helicates feature two hexa‐coordinated MII ions (M=Fe, Zn, or Mn), which are embedded in a macrobicyclic ligand frame ...

Carbon dioxide reduction by lanthanide(iii) complexes supported by redox-active Schiff base ligands

Rosario Scopelliti, Marinella Mazzanti, Davide Toniolo, Nadir Jori

Here we have explored the ability of Schiff bases to act as electron reservoirs and to enable the multi-electron reduction of small molecules by lanthanide complexes. We report the reductive chemistry of the Ln(iii) complexes of the tripodal heptadentate S ...

Stabilization of the Oxidation State plus IV in Siloxide-Supported Terbium Compounds

Rosario Scopelliti, Marinella Mazzanti, Ivica Zivkovic, Aurélien René Willauer

The synthesis of lanthanides other than cerium in the oxidation state +IV has remained a desirable but unmet target until recently, when two examples of Tb-IV with saturated coordination spheres were isolated. Here we report the third example of an isolate ...

CS2 Reductive Coupling to Acetylenedithiolate by a Dinuclear Ytterbium(II) Complex

Rosario Scopelliti, Marinella Mazzanti, Julie Renée Michelle Andrez, Davide Toniolo

The activation of CS2 is of interest in a broad range of fields and more particularly in the context of creating new C‐C bonds. The reaction of the dinuclear ytterbium(II) complex [Yb2L4], 1, (L = (OtBu)3SiO‐) with carbon disulphide led to the isolation of ...
