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 ...

High-performance polyamides with engineered disorder

Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Nicolas Candau, Sylvain Cyril Claude Galland, Julien Philippe Cretenoud

The extraordinary property profiles of many biological materials derive from their hierarchical structure and control of order and disorder at different length scales. Application of these concepts to the design of synthetic polymers may provide new routes ...

Semiaromatic Polyamides and Copolyamides Comprising Kinked Repeating Units

Julien Philippe Cretenoud

The replacement of metals with polymer-based materials is considered to be key to reducing weight, cost, and cycle times in different technological applications, including the automotive and aerospace industries. Semiaromatic polyamides are particularly at ...

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 ...
