New organometallic derivatives of helicenes containing platinum and ruthenium centers have been prepared and theirs chiroptical properties have been studied. In the...

This thesis addresses the problem of diffusive transport in multilayer systems when the layers thickness is of the order of or even smaller than the mean free path. We...

The key issue for realizing the potential of carbon nanotubes has always been, and still remains, a better control of their growth and in particular the selective...

In a first part of this work, we studied the effect of the alkoxy chains length and the position of the fluor on the physical properties and on the sequence phases of...

This PhD work is devoted to the use of chiral counterion in asymmetric organometallic catalysis. The synthesis of the chiral silver phosphate Ag(S)TRIP was first...

Ce travail présente les principes et quelques applications de la spectroscopie par génération de fréquence somme visible-infrarouge (SFG) non conventionnelle. Après...

Sorting biological molecules according to their chirality appears a challenge for the parmaceutical industries. Chiral carbon nanotubes formed by rolling up grapheme...
