Applications
9,10-Bis[N,N-di-(p-tolyl)-amino]anthracene, TTPA, is commonly used as a green dopant material in TADF-OLED devices.
Bearing two triarylamine units, TTPA is also electron-rich in nature. It can be used as a hole-transporting material for OLED, OPV and perovskite solar cell applications.
