title: Synthesis of disilanyl double-pillared bisdibenzofuran with a high triplet energy.
abstract: A double-pillaring strategy for the synthesis of silacyclophanes has been applied to dibenzofuran to create a new cyclophane molecule that links two dibenzofuran molecules through σ(SiSi)-π conjugation. The performance of disilanyl double-pillared dibenzofuran [(Si)DPBD(O)] in green phosphorescent organic light-emitting diode (OLED) devices was evaluated as both a carrier-transport material and a host material for an Ir-based phosphorescent emitter.
