Semiaromatic Polyamides with Re-Entrant Chain Folding Templated by "U-Turn" Repeat Units

Rosario Scopelliti, John Christopher Plummer, Farzaneh Fadaei Tirani, Holger Frauenrath, Bilal Özen, Julien Philippe Cretenoud, Michael Alan Giffin

Biopolymers often show deterministic chain folding templated by repeat unit sequences whose conformations are locked in by intramolecular interactions. In this work, we have used repeat units based on rigid anthracene or acridine scaffolds, which we refer ...

Structure-Property Relationships in Bithiophenes with Hydrogen-Bonded Substituents

Rosario Scopelliti, Kurt Schenk, Farzaneh Fadaei Tirani, Holger Frauenrath, Anne-Clémence Corminboeuf, Kun-Han Lin, Bilal Özen

The use of crystal engineering to control the supramolecular arrangement of pi-conjugated molecules in the solid-state is of considerable interest for the development of novel organic electronic materials. In this study, we investigated the effect of combi ...

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

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

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 ...

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

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

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 ...

Synthesis and Characterisation of Semiaromatic Polyamides Comprising Benzofurobenzofuran Repeating Units

Rosario Scopelliti, Farzaneh Fadaei Tirani, Holger Frauenrath, Anne-Clémence Corminboeuf, Daniel Görl, Alberto Fabrizio, Bilal Özen, Thomas Schmaltz, Julien Philippe Cretenoud

Semiaromatic polyamides are attractive engineering polymers owing to their outstanding thermo-mechanical properties. To expand the scope of semiaromatic polyamides by additional optoelectronic features, one may consider the incorporation of extended pi-con ...
