Application

2PXZ-OXD can be employed in organic light-emitting diodes (OLEDs) as an electron-transport layer, facilitating the efficient injection and transport of negative charges (electrons) from the cathode to the emissive layer. 2PXZ-OXD exhibits good electron mobility and excellent electron-blocking properties, contributing to improved charge transport and overall device performance in OLEDs. Furthermore, 2PXZ-OXD can be utilized in studies such as organic photovoltaic (OPV) devices and organic field-effect transistors (OFETs) due to its electron transport and blocking characteristics.
Use as TADF Green Dopant, with a EQE of 14.9%.
