N4,N4,N4',N4'-tetra([1,1'-biphenyl]-4-yl)-[1,1'-biphenyl]-4,4'-diamine Usage And Synthesis

Description

N4, N4, N4', N4'-tetra([1,1'-biphenyl]-4-yl)-[1,1'-biphenyl]-4,4'-diamine (or BPBPA) is an Electron-Rich Triarylamine Derivative with two amines substituted by four biphenyl groups. It is commonly used as a hole transport layer (HTL) material in OLEDs. BPBPA demonstrates high charge carrier mobility of 1.74 ×10?2 cm2/V?s, enabling rapid hole extraction from the adjacent donor layer. This results in an enhanced open-circuit voltage and improves powder conversion efficiency (PCE) of 9% with reference devices.
