The journal Chemistry. A European Journal features in its COVER the recently published article “An enantiopure propeller‐like trityl‐brominated radical: Bringing together a high racemization barrier and an efficient circularly polarized luminescent magnetic emitter” authored by rearserchers of NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit, led by Jaume Veciana (CIBER-BBN, ICMAB-CSIC)
Nowadays, it is necessary to know the increasingly specific requirements of electronic devices in order ot be able to find new multifunctional materials that allow obtaining more efficient devices. This article represents a step forward in the field of organic free radicals. Organic free radicals act as polarized light emitters synthesizing and studying the two optically active enantiomers of a new brominated derivative of the trityl radical, which show no evidence of racemization up to 60 ° C for more than two hours, due to the great steric hindrance imposed by the bulky atoms of Br that have as substituents. This fact has allowed to determine its great efficiency of luminescence of polarized light despite its purely organic nature. In addition, this result suggests that new, very improved radicals can be obtained thanks to the wide synthetic possibilities offered by Br atoms.
