Organic Light Emitting Diodes Using a Neutral pi Radical as Emitter: The Emissio

Triplet harvesting is a main challenge in organic light-emitting devices (OLEDs), because the radiative decay of the triplet is spin-forbidden. Here, we propose a new kind of OLED, in which an organic open-shell molecule, (4-N-carbazolyl-2,6-dichlorophenyl) bis(2,4,6-trichlorophenyl)methyl (TTM-1Cz)
