Description

Description générale

2,2′-Dimethyl-N,N′-di-[(1-naphthyl)-N,N′-diphenyl]-1,1′-biphenyl-4,4′-diamine (α-NPD) is a conducting polymer that can be used as a hole transporting material (HTM) with a transport gap of _~4 eV and an ionization potential of 5.5 eV.

Application

α-NPD can be used as a π-conjugated organic semiconducting material which has good charge transporting properties. It can be used in the fabrication of organic electronic devices such organic light emitting diodes (OLEDs) and organic solar cells (OSCs).

This material is used as a high performance host material for OLED devices showing increased device efficiency (maximum luminance efficiency was 4.4 cd/A at 9 V for the fluorescent device and 24.4 cd/A for phosphorescent device).
