Amine‐Based Interfacial Molecules for Inverted Polymer‐Based Optoelectronic Devices

Abstract

The change in the work function (WF) of ZnO with amine-based interfacial mole-cules (AIM) can be controlled by the number of amine groups. AIM with a larger amine group can induce a stronger interface dipole between the amine groups and the ZnO surface, leading to a greater reduction of the WF.
