Webb6 dec. 2024 · Here, this work presents an air-stable ultrabright inverted organic light-emitting device (OLED) by using zinc ion-chelated polyethylenimine (PEI) as electron injection layer. The zinc chelation is demonstrated to increase the conductivity of the PEI by three orders of magnitude and passivate the polar amine groups. With these … WebbThe crude organic extract will contain impurities that were not removed in the aqueous layer. After concentration of the organic phase using a rota-vap (rotary evaporator), there will be “brown gunk” in the bottom of the flask that will require further purification.
