合成了具有电致发光特性的新型共轭桥联苯并菲衍生物。六步合成产生氰基甲基三亚苯衍生物(7a-7d)。通过应用与烷氧基取代的二醛8的Knoevenagel反应将它们缩合成PPV类似短链化合物9a-9d。产物9a-9d显示出明亮的橙色至红色光致发光。它们适合作为有机发光二极管 (OLED) 的发射层，无论是单层还是双层排列，并以铜酞菁作为空穴传输层。
Novel conjugated-bridged triphenylene derivatives with electroluminescent properties were synthesized. A six step synthesis yields the cyanomethyltriphenylene derivatives (7a-7d). These were condensed by applying a Knoevenagel reaction with the alkoxy substituted dialdehyde 8 to PPV analogous short chain compounds 9a-9d. The products 9a-9d show bright orange to red photoluminescence. They are suitable as the emissive layer in organic light-emitting diodes (OLEDs), both in single and double layer arrangements with copper phthalocyanine as the hole transport layer.
