Application

N4,N4,N4′,N4′-Tetra[(1,1′-biphenyl)-4-yl]-(1,1′-biphenyl)-4,4′-diamine, also known as BPBPA, is a Hole Transport, Electron Blocking Layer (HTL / EBL) material. BPBPA is popularly used in optoelectronic devices, such as high efficiency and long lifetime light-emitting diode devices (organic LEDs, OLEDs).
N4,N4,N4′,N4′-Tetra[(1,1′-biphenyl)-4-yl]-(1,1′-biphenyl)-4,4′-diamine is used as a hole transport material or as a host material in the emissive layer of organic light-emitting diodes (OLEDs) devices. Its semiconducting properties suits for R&D studies in organic field-effect transistors(OFETs) and thin-film transistors (TFTs).
