Heterogeneous Overhauser-DNP on H-1 dominated by scalar coupling in aqueous solution

Jean-Philippe Ansermet, Christophe Roussel, Jonas Milani, Felipe Andres Saenz Padilla

The Overhauser Dynamic Nuclear Polarization (O-DNP) of H-1 nuclei usually involves a dipolar coupling with the polarizing agent, whereas scalar coupling via hyperfine interactions are more common with C-13 nuclei. Here, we show a scalar-coupling dominated ...

Blatter-type radicals as polarizing agents for electrochemical overhauser dynamic nuclear polarization

Jean-Philippe Ansermet, Christophe Roussel, Jonas Milani, Holger Frauenrath, Felipe Andres Saenz Padilla, Mika Antero Tamski

Overhauser dynamic nuclear polarization (O-DNP) refers to a microwave-assisted process where an unpaired electron's (e.g. a radical) spin polarization is transferred to surrounding nuclei in solution, thus increasing the nuclear magnetic resonance (NMR) si ...

Block Copolymer Stabilized Liquid Nanodroplets Facilitate Efficient Triplet Fusion-Based Photon Upconversion in Solid Polymer Matrices

Felipe Andres Saenz Padilla

Sensitized triplet-triplet annihilation-based photon upconversion is a photo-physical process that affords anti-Stokes-shifted emission after annihilation of two metastable triplet excitons of an emitter dye and the formation of a fluorescent singlet state ...

Heterotetracenes: Flexible Synthesis and in Silico Assessment of the Hole Transport Properties

Kevin Sivula, Anne-Clémence Corminboeuf, Jérôme Waser, Xavier Adrian Jeanbourquin, Yifan Li, Felipe Andres Saenz Padilla, Ganna Gryn'ova

Thienoacenes and furoacenes are among the most frequent molecular units found in organic materials. The efficient synthesis of morphologically different heteroacenes and the rapid determination of their solid-state and electronic properties are still chall ...
