Mechanism of Ir (ppy)3 Guest Exciton Formation with the Exciplex ...
May 25, 2022Because Ir(ppy) 3 and TPBI molecules are spatially quite close to each other in 1 (TCTA/TPBI/Ir(ppy) 3) and because the HOMO-LUMO gap involving the two molecules is rather small, as shown in Figure S1, the lowest 1 (G + /A −) state can actually be lower in energy than the lowest 1 (D + /A −) state.

Multiple exciton generation
The multiple exciton generation threshold in SWNTs can be close to the limit defined by energy conservation. Double-exciton generation has additionally been observed in organic pentacene derivatives through singlet exciton fission with extremely high quantum efficiency wikipedia.org
