Title:Molecular and supramolecular strategies for highly luminescent trityl radical and their sensing applications
Date: Friday 19th May Time: 11:00 am Place: Sala d'Actes Carles Miravitlles (ICMAB)
The luminescence properties of some trityl radicals were evaluated in organic nanoparticles (ONPs) and polymeric films. For the first time, excimers from supramolecular and stable radical pairs were observed and characterized. This study allowed to design and synthesize a new excimer-forming trityl radical, the tris(2,4,6 tribromophenyl)methyl radical, which was the first example of a polybromotriphenylmethyl radical. This molecule exhibited improved optical properties and chemical versatility compared with the chlorinated species. Finally, the dual emission (monomer and excimer) of radical-doped ONPs was used for the development of high-sensitive luminescence nanothermometer for biological applications.
