Plexcore® OC, an aqueous hole injection layer (HIL), is a tunable ink platform that offers a wide range of work functions (−5.3 to − 5.7 eV by AC2) and resistivities (100 to >10,000 Ohm‐cm) to extend device lifetime and performance with various emitter technologies. Other properties include low acid content, excellent transparency in the visible spectrum (>90%), tunable viscosity (6–30 cP) for various coating applications and low surface roughness (Rq < 10 nm) to minimize defects. Plexcore® OC is demonstrated to provide improved stability to de‐doping phenomena, even at fields of 60 kV/cm. Additionally, the relative voltage stability using Plexcore® OC in a typical POLED has been demonstrated to be less than 0.5V over the life of the device.
