PPT (CAS number 1019842-99-9) is an ambipolar phosphorescent host material with an electron-rich dibenzothiophene core and two electron-deficient diphenyl-phosphoryl side arms. For this reason, PPT is a good electron-transport material with higher electron mobility rate, offering better electron injection.
Its wide bandgap and high triplet energy level creates highly-efficient TADF-OLED devices, PPT is normally used to host blue light-emitting materials (such as FIrPic). PPT is also used with electron-donating materials to form exciplexes with delayed fluorescence to enhance electroluminescence efficiency.
PPT is one the first reported organic LPL (OLPL) systems of two simple organic molecules that are free from rare elements such as strontium, europium and dysprosium. With a simple structure that is easy to fabricate, the device of OLPL system can generate emission lasting for more than an hour at ambient temperatures.
