Usage

Description

N1,N1'-(biphenyl-4,4'-diyl)bis(N1-phenyl-N4,N4-di-m-tolylbenzene-1,4-diamine), also known as DNTPD, is a hole transporting material with good optical properties. It has high ionization energy (IE) and hole mobility, which allow excellent performance for electron blocking. Bearing four triarylamine units, DNTPD is electron-rich and is an extended structure of TPD and NPB that is widely used in organic electronics.

Uses

Used in Optoelectronic Applications:
DNTPD is used as a hole transport layer material for its high ionization energy and hole mobility, which contribute to its excellent electron blocking performance. This makes it suitable for use in the fabrication of high-efficiency organic light-emitting diodes (OLEDs) and perovskite solar cell devices.
Used in Display Industry:
In the display industry, DNTPD is used as a hole transport or hole injection layer material in OLED devices. Its electron-rich nature and extended structure of TPD and NPB make it a valuable component in the development of advanced display technologies.
Used in Solar Energy Industry:
DNTPD is also utilized in the solar energy industry, particularly in the development of perovskite solar cells. Its role as a hole transport layer material enhances the efficiency and performance of these solar cell devices.
