L'électrochimie : de l'électron aux smartphones
- (Pint of science, Lyon, 15th May 2017)
À priori, rien ne semble relier nos smartphone, la botanique et le service des urgences. Et pourtant, tous ces domaines ont en commun le partage -- non pas d'une bière -- mais de quelque chose d'encore plus simple : l'électron. Nous verrons à quel point les applications de cette science -- l'électrochimie -- sont variées et originales.

The importance of the multiconfigurational description of the junction electronic structure is investigated in quantum transport through molecular devices. Using an accurate wavefunction-based description of the low-energy spectroscopy, transport through a 2-electron/2-molecular orbital prototype is evaluated, covering lowly – H2-like – to highly – O2-like – correlated regimes. The contributions arising from the presence of competing singlet and triplet states in magnetic systems are analyzed. It is shown that the electronic conductivity provides a signature of the full multiplet energy spectrum, as well as of the multideterminant structure of wavefunctions.

Chemistry of stable radicals opened a new insight for spintronics. The unpaired electron on an organic molecule is responsible for multiple properties : magnetism, conductivity, absorbance. Despite the abundance of experimental data, electronic phenomena linked to those properties are not yet fully understood. The further development of radical chemistry requires a deeper understanding thanks to high level computations. Thanks to these calculations, chemists will be able to fully master the properties of this family of molecules.
