Application

N4,N4′-Bis(4-(6-((3-ethyloxetan-3-yl)methoxy)hexyl)phenyl)-N4,N4′-diphenylbiphenyl-4,4′-diamine (OTPD) is a solution-processable Hole Transport / Electron Blocking Layer (HTL / EBL) material popularly used in optoelectronic devices, such as diodes and solar cells .
N4,N4′-Bis(4-(6-((3-ethyloxetan-3-yl)methoxy)hexyl)phenyl)-N4,N4′-diphenylbiphenyl-4,4′-diamine can be used in studies of organic light-emitting diodes (OLEDs) and organic photovoltaic (OPV) devices as a hole transport material. Its favorable charge transport characteristics make it suitable for enhancing the charge collection efficiency and overall power conversion efficiency of OPV devices.
