New Hole Transport Layers containing azomethine bonds for incorporation in Organic Light Emitting Diodes
DFT study of a dihydrocobalt catalyst. Dihydridocobalt catalysts are known in the literature to generate dihydrogen by reductive elimination. Following the discovery of a complex of this type, by Louis Fensterbank’s group, that did not allow the production of hydrogen, an analysis of the catalytic cycle mechanism seemed necessary. Tetrakistrimethylphosphine cobalt catalyst was used to do the hydrosilylation reaction of an alkyne. My project consisted to model the catalytic cycle to determine why dihydrogen was not observed experime ntally.
Synthesis of di-block molecules presenting good opto-electronic properties for electrochromic devices. In order to address the stringent reaction conditions for preparing conventional conjugated materials constituted of vinyl groups (-CH=CH-), the Skene’s group is opting for easily prepared azomethines (-N=CH-). While they are synthetically easier to prepare than conventional materials, they have the added advantage of being air stable. The first two months of the internship was dedicated to synthesis of new di-block molecules and the development of efficient purification methods. All the di-blocks, consisting of complementary amine and aldehyde, were prepared as monomers that could self- condense. The effect of different electronic groups and aromatics on the optical, electrochemical and spectroelectrochemical properties was investigated. The capacity of these monomers to undergo self-polymerization directly on electrodes was also examined along with their use as electroactive layers capable of undergoing reversible color switching.
Computational study of moderately strong phenols’ dissociation in water to understand the mechanism of the reaction. Eigen introduced the mechanism of acid-base reaction (in aqueous solution) in his work 50 years ago. He mentioned that the proton transfer was executed in two steps. In the past years, many researchers studied again this mechanism by means of ultrafast time-resolved spectroscopy and some of the results were contradictory. We decided to study once more this mechanism from a theoretical point of view.
