Résumé

This research thesis is focusing on the synthesis and studies of novel organic materials for organic electronics applications. In particular, we will create doped hexa-peri-hexabenzocoronenes (HBCs) featuring an alternating B-N cycle, or borazinic cycle, forming hexa-peri-hexabenzoborazinocoronenes (HBBNCs). Three synthetic pathways leading to the target HBBNCs will be developed: one will use hexasubstituted borazines as building blocks; the second will go through the construction of a spherand-like cyclohexa-meta-phenylene; and the last will make use of azaborine-type precursors, which was developed in collaboration with François Simon, master student from the University of Namur. The fourth and last chapter of the manuscript will delve into molecule-substrate interface studies we realised by scanning tunnelling microscopy and X-ray photoelectron spectroscopy on borazine derivatives, in collaboration with Dr. Simon Kervyn de Meerendré, a former member of our group who kickstarted the synthesis of borazinic compounds, the group of Prof. Dr. Giovanni Costantini (University of Warwick, United Kingdom) who performed the STM measurements, the group of Prof. Dr. Alessandro De Vita who undertook the theoretical studies (King’s College London, United Kingdom), and the SuperESCA beamline of Elettra Sinchrotrone, Trieste, Italy.
