Application

Hole Transport/Electron Blocking Layer (HTL/EBL) for Efficient Organic Light Emitting Diode (OLED).
N,N′-Bis(naphthalen-1-yl)-N,N′-bis(phenyl)-2,2′-dimethylbenzidine can be used in organic light-emitting diodes (OLEDs) as a hole transport material. It has a suitable energy level and molecular structure that allows for effective energy transfer to dopant molecules, leading to enhanced electroluminescence and color purity in OLED devices. Due to its excellent charge transport properties and sensitivity to light, it can be used in studies such as organic photodetectors. It can be used as an active layer or part of the photodetection device structure, enabling efficient charge generation and transport upon light exposure.
