We synthesized a new set of solution processable light emitting materials for phosphorescent red organic light emitting diodes (OLEDs). To improve the device performance, we controlled the electron mobility of electron transport layer (ETL). However, the effect of changing the electron mobility of ETL was very limited. So, we applied a new crosslinkable hole transport layer which was perfectly crosslinked at 135°C and achieved much more improved efficiency by up to 200%.
