Phosphorescent Organic Light-Emitting Diodes (PhOLEDs) represent a significant leap in energy efficiency compared to their fluorescent counterparts, capable of achieving internal quantum efficiencies close to 100%. This remarkable performance is largely attributed to the use of phosphorescent emitters, which can harvest both singlet and triplet excitons. However, to fully capitalize on this potential, specific host and transport materials with high triplet energies are indispensable. TmPyPB, or 3-[3-[3,5-bis(3-pyridin-3-ylphenyl)phenyl]phenyl]pyridine (CAS No.: 921205-03-0), supplied by NINGBO INNO PHARMCHEM CO.,LTD., is a prime example of such a crucial material.

The fundamental principle behind using high triplet energy materials in PhOLEDs is to prevent energy transfer from the phosphorescent emitter to the host or transport layers. If the triplet energy level of the host or transport material is lower than that of the emitter, energy can be dissipated non-radiatively, leading to reduced device efficiency and brightness. TmPyPB possesses a notably high triplet energy level, effectively acting as an energy barrier. This characteristic makes it an excellent choice for host materials or as an electron transport layer that also performs hole and exciton blocking, ensuring that energy remains concentrated within the emissive layer to produce light.
