Isolation of 1,4,5,8-tetraazanaphthalene radicals

Chem. Commun., 2025, Advance Article DOI: 10.1039/D5CC03096J, Communication Saroshan Deshapriya, Selvan Demir The first 1,4,5,8-tetraazanaphthalene radicals were isolated and analysed through crystallography, EPR spectroscopy, DFT computations. The radicals exhibit electrical conductivity at room temperature, placing them among elemental semiconductors.
