Siloles attached to phenylene ethynylene strands were prepared successfully by Sonogashira coupling of 2,5-dibromosilole with ethyne-terminated phenylene ethynylenes. Elongation of the arylene ethynylene chain involving up to at least three aromatic rings leads to high quantum yields in solution.
通过Sonogashira耦合2,5-二溴硅烯与末端为乙炔的苯乙炔链成功制备了附着在苯并乙炔链上的硅烯。芳烃乙炔链的延伸,涉及至少三个芳香环,导致在溶液中具有高的量子产率。
