摘要：Several new enediynes with long chain alkyl groups were synthesized through Sonogashira coupling reactions between long chain alkynes and（Z）-1,2-dichloroethene. These enediynes（1） were then subjected to thermal Bergman cyclization in a refluxing diphenyl ether bath under vacuum to obtain conjugated polyphenylenes with the weight-average molecular weights up to 4.9 × 103 g·mol·1. The occurrence of Bergman cyclization was confirmed by 1H-NMR, 13C-NMR, and IR spectroscopic analysis. These polyphenylenes are fully soluble in common organic solvents and exhibit good thermal stability. The optical properties of the polyphenylenes were investigated by UV-Vis absorption and photoluminescence（PL） spectroscopies. A blue emission was observed for all these polyphenylenes.
