摘要：

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.
