High, Anisotropic, and Substrate-Independent Mobility in Polymer Field-Effect Transistors Based on Preassembled Semiconducting Nanofibrils

Achieving nanoscale control over the crystalline structure and morphology of electroactive polymer films and the possibility to transfer them onto any solid substrate are important tasks for the fabrication of highperformance organic/polymeric field-effect ...

Donor-acceptor stacking arrangements in bulk and thin-film high-mobility conjugated polymers characterized using molecular modelling and MAS and surface-enhanced solid-state NMR spectroscopy

David Lyndon Emsley

Conjugated polymers show promising properties as cheap, sustainable and solution-processable semiconductors. A key challenge in the development of these materials is to determine the polymer chain structure, conformation and packing in both the bulk polyme ...

A facile synthetic strategy to polysiloxanes containing sulfonyl side groups with high dielectric permittivity

The chemical modification of polymers with lateral polar groups increases their dielectric permittivity above the glass transition temperature, making them attractive materials for dielectric elastomer actuators. Despite the large dipole moment of the sulf ...

Charge migration and charge transfer in molecular systems

Majed Chergui, Ursula Röthlisberger, Jacques-Edouard Moser, Andrea Cannizzo, Natalie Renuka Banerji, Joël Teuscher, Christopher Alexander Arrell, Pablo Lopez Tarifa, Elisa Liberatore

The transfer of charge at the molecular level plays a fundamental role in many areas of chemistry, physics, biology and materials science. Today, more than 60 years after the seminal work of R. A. Marcus, charge transfer is still a very active field of res ...

Synthesis of Responsive Two-Dimensional Polymers via Self-Assembled DNA Networks

Duncan Thomas Lindsay Alexander, Ulrich Aschauer, Hao Yu

Despite a growing interest in two-dimensional polymers, their rational synthesis remains a challenge. The solution-phase synthesis of a two-dimensional polymer is reported. ADNA-based monomer self-assembles into a supra-molecular network, which is further ...

Salt-induced thermochromism of a conjugated polyelectrolyte

Natalie Renuka Banerji, Laurent Alexis Clément Vannay, Yauhen Sheima

We report here the photophysical properties of a water-soluble conjugated polythiophene with cationic side-chains. When dissolved in aqueous buffer solution (PBS, phosphate buffered saline), there is ordering of the polymer chains due to the presence of th ...

All-diamond functional surface micro-electrode arrays for brain-slice neural analysis

Ladislav Kavan, Michele Giugliano

Diamond-based microelectrode arrays were fabricated by using nanocrystalline diamond as an insulating layer and conductive boron-doped in order to used them for analysis of brain cortical slices. MEA surface is solely composed of diamond, exposed to the ce ...

Guanidinium can both Cause and Prevent the Hydrophobic Collapse of Biomacromolecules

Halil Ibrahim Okur

A combination of Fourier transform infrared and phase transition measurements as well as molecular computer simulations, and thermodynamic modeling were performed to probe the mechanisms by which guanidinium (Gnd(+)) salts influence the stability of the co ...

Morphology stabilization strategies for small-molecule bulk heterojunction photovoltaics

Kevin Sivula, Liang Yao, Xavier Adrian Jeanbourquin, Simon Hänni, Arvindh Sekar, Emilie Aude Marie Ripaud

The greater crystallinity of solution-processed small-molecule organic semiconductors, compared to their polymer counterparts, renders the bulk heterojunction (BHJ) more susceptible to phase separation under thermal stress, decreasing device performance. H ...

Method and device for fabrication of 3d multi - material (composite) parts by selective laser melting combined with laser welding and cutting

Roland Logé, Nikola Kalentics

The method of manufacturing objects made of a first primary material such as ceramic, metallic or polymer materials on at least one workstation by selective laser melting (SLM) comprises the addition of at least a secondary material different from the prim ...
