[60]Fulleropyrrolidine-containing poly(benzyl ether) dendrimers 1−4 were synthesized via 1,3-dipolar cycloaddition of amino acid and aldehyde derivatives and [60]fullerene. Their dielectric and electrooptical (Kerr effect) solution properties were studied and compared with poly(propyleneimine) dendrimers, namely DAB-dendr-(alkyl chain)n and...

In situ attenuated total reflection infrared spectroscopy in a flow-through cell combined with online UV−vis spectroscopy was used to investigate the oxidation of 2-propanol over Pd/Al2O3 catalyst. The state of the catalyst was driven fast between reduced and oxidized by admitting alternately dissolved hydrogen and oxygen, and the response of the catalytic solid−liquid...

Synthesis and characterization of new hexabenzocoronene (HBC) derivatives bearing perfluoroalkylated chains are described. These disc-shaped polycondensed aromatic hydrocarbons are known to self-assemble by π-stacking into columnar architectures. The peripheral decoration with perfluorinated chains, well-known for their low van der Waals forces, leads as expected to reduced intercolumnar...

Mémoire de Master Advanced Studies (MAS) : Haute école pédagogique du canton de Vaud, 2011 ; mp5299.
Ce mémoire professionnel s’est intéressé à l’étude des molécules de la vie quotidienne (dans la discipline chimie), par les élèves gymnasiens de 1re année voie diplôme. Il s’agissait, dans ce contexte, de savoir si l’élaboration d’exposés individuels est un bon moyen d’apprentissage, et comment en tirer parti au mieux. Ce travail avait une finalité didactique et...

Two fullerene–peralkylated ferrocene derivatives were synthesized: (1) a liquid-crystalline dyad (compound 1) was obtained by introduction of nonamethyl ferrocene into a liquid-crystalline fullerene derivative and (2) a reference compound (compound 2) was synthesized by attachment of nonamethyl ferrocene to a fulleropyrrolidine. The liquid-crystalline dyad displayed an enantiotropic smectic A...

Thèse de doctorat : Université de Neuchâtel, 2006 ; 1873.
Depuis la découverte des cristaux liquides au XIXième siècle, leur intérêt n’a cessé de croître, menant à des applications toujours plus nombreuses. Très répandue dans la nature, l’architecture dendritique a permis de rendre mésomorphe l’objet anisotrope qu’est le fullerène, celui-ci, dont les propriétés photophysiques sont des plus enthousiasmantes, a souvent été lié à...
