OXD-7(CAT: M440006) is a widely used electron-transport and host material in organic optoelectronic devices. Featuring an oxadiazole-based structure, OXD-7 provides excellent electron mobility, high triplet energy, and strong thermal stability, making it particularly effective in multilayer organic light-emitting diodes (OLEDs). Its rigid backbone and favorable energy-level alignment enhance charge balance, reduce exciton quenching, and improve device efficiency and lifetime. OXD-7 also serves as a versatile host for phosphorescent and thermally activated delayed fluorescence (TADF) emitters. With strong film-forming properties and compatibility in complex device architectures, OXD-7 remains a benchmark material for next-generation display and optoelectronic applications.
