4,5-bis(carbazol-9-yl)-1,2-dicyanobenzene Usage And Synthesis
DescriptionAs a thermally activated delayed fluorescence (TADF) emitter [4,5-di (9H-carbazol-9-yl) phthalonitrile (2CzPN)], it can enhanced performance of small molecule organic solar cells.  The absorption spectrum of 2CzPN is complementary with the donor SubPc, and its photoluminescence spectrum overlaps with the absorption spectrum of the active layer.  The estimated hole injection barrier slightly increases from 0.809?eV (without 2CzPN) to 0.874?eV (with 5?nm 2CzPN) and the hole mobility simultaneously decreases.
