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.
双支柱策略被应用于二苯并呋喃的合成中，以创造一种新的环芳烷分子，该分子通过σ(Si-Si)-π 共轭将两个二苯并呋喃分子连接起来。二硅基双支柱二苯并呋喃[(Si)DPBD(O)]在绿色磷光有机发光二极管(OLED)器件中的性能被评估为一种载流子传输材料和一种基于 Ir 的磷光发射体的主体材料。
