Manipulating the Local Light Emission in Organic Light‐Emitting Diodes by using Patterned Self‐Assembled Monolayers

Abstract: Patterned organic light-emitting diodes are fabricated by using microcontact- printed self-assembled monolayers on a gold anode (see background figure). Molecules with dipole moments in opposite directions result in an increase or a decrease of the local work function (foreground picture), providing a direct handle on charge injection and enabling local modification of the light emission.

“…By the absorption of a self-assembled monolayer (SAM), the effective work function of Au can be increased by 0.9 eV or decreased by 0.45 eV [20][21][22]. Similar work function changes have been reported for silver electrodes covered with a SAM.…”

“…Examples range from thiols on gold, [3][4][5][6][7][8] to silanes on hydroxyl-terminated surfaces, [11,12,15,17] to mixtures of SAMs containing different terminal functional groups on metal oxide buffer layers. [13] A number of groups have incorporated SAMs into OLEDs, [1][2][3][4]6,[10][11][12]18,19] with many focusing on the use of phosphonic acid SAMs to modulate interfacial properties and improve device performance. [20][21][22][23][24][25][26] Given the strong influence SAM modifiers can have on the performance of organic electronic devices, the ability to microcontact print SAMs with large work function contrast is both scientifically interesting from the standpoint of creating model systems to explore the role of barriers and energy level offsets on charge injection in OLEDs, and technologically useful in the context of applications including low-cost illuminated signs and displays.…”

[3,6] Although a limited amount of work has been performed in this area, notably by microcontact printing thiols on gold, [3,6] silanes on hydroxyl-terminated surfaces, [2,11,12] or phosphoryl chlorides on indium tin oxide (ITO), [27] these functional group/substrate combinations are not necessarily ideal for integration into OPV and OLED applications. First, transparent conductive oxides are more commonly used than gold as the anode in OPVs and OLEDs.…”
