1,3-Bis[3,5-di(pyridin-3-yl)phenyl]benzene (BmPyPhB)(CAT: M440013) is a high-performance organic electron-transport and host material widely employed in optoelectronic devices. Its rigid aromatic backbone and multiple pyridyl substituents provide excellent electron affinity, high triplet energy, and strong thermal stability, making it especially suitable for multilayer organic light-emitting diodes (OLEDs). BmPyPhB is frequently used as a host for phosphorescent and thermally activated delayed fluorescence (TADF) emitters, where it enhances charge balance, reduces exciton quenching, and supports extended device lifetimes. With reliable film-forming ability and efficient electron transport, BmPyPhB is a benchmark material in next-generation OLED displays, lighting, and advanced optoelectronic technologies.
