Abstract

In this paper, we report the fabrication of small-molecule-based thin-film layers with a thickness of several tens of nanometers on a release layer by bar coating and subsequent stacking onto other organic layers by the developed film transfer method using driving belts and rollers as a prototype roll-to-roll technique. We use novel thermally activated delayed fluorescence (TADF) materials in this process, achieving multilayered organic light-emitting diodes (OLEDs) with high external quantum efficiency (EQE), which is comparable to those of OLEDs prepared by conventional vacuum deposition. The developed film transfer method shows great potential to realize OLEDs with high efficiency at low cost.
