In particular, it was found that the incorporation of (PLAGH)2[ZnCl4] at the polymer/Al interface improved the luminous efficiency of the device (from 2.6 to 3.32 cd/A) and reduced the turn-on voltage, whereas an up to threefold increase in brightness (∼14,106 cd/m2 for (PLAGH)2[ZnCl4], as compared to ∼5850 cd/m2 for the reference device) was observed after annealing at 110 ºC.

Abstract

Herein (PLAGH)2[ZnCl4] (PLAGH+ = pyridoxalaminoguanidinium cation) is introduced as a new electron injecting layer for efficient polymer light emitting diodes based on the green-emitting copolymer poly[(9,9-dioctylfluorenyl-2,7-diyl)-co-(1,4-benzo-2,1′,3-thiadiazole)] (F8BT). The device structure is glass/ITO/PEDOT:PSS/F8BT/(PLAGH)2[ZnCl4]/Al, where (PLAGH)2[ZnCl4] was deposited from its water/methanol solution via spin-coating. In particular, it was found that the incorporation of (PLAGH)2[ZnCl4] at the polymer/Al interface improved the luminous efficiency of the device (from 2.6 to 3.32 cd/A) and reduced the turn-on voltage, whereas an up to threefold increase in brightness (∼14,106 cd/m2 for (PLAGH)2[ZnCl4], as compared to ∼5850 cd/m2 for the reference device) was observed after annealing at 110 ºC.
