Tailored materials for Sustainable Technologies: programming functional molecular components through Boron-Nitrogen doping
The scientific goal of the STiBNite Research Training Network is to develop and apply a bottom-up covalent synthesis and assembly approach to produce advanced organic semiconductors with precisely controllable properties, achieved by perfect positional control of dopant atoms. We plan to produce boron-nitrogen-carbon (BNC) macromolecular materials, either in solution or on surface, starting from programmed polycyclic aromatic hydrocarbons precursors substituted in given positions with BN-doping units (i.e., borazine rings, B3N3). Each will be encoded with a specific BN-doping pattern and concentration to control its optoelectronic and thermal properties. In particular, insertion of borazine rings, which have an insulating, polar character, will disrupt the π-conjugation of the host carbon framework hence tuning its bandgap. These BN-doped PAHs will be developed into either covalent or non-covalent bidimensional materials (2DMs), or transformed into nanoparticles (BNCNPs), characterized by fully reproducible properties.
