摘要：
The linear hexamer, tetramer, and octamer of thiophene have been synthesized by ferric acetylacetonate dimerization of the appropriate organolithium precursors, followed by extensive purification. On/off ratios and hole mobilities of these compounds in thin-film transistors are significantly higher than previously reported. In particular, a hexamer sample with on/off ratio > 10(6) and intrinsic behavior has been obtained, and the mobility of the octamer is unexpectedly high.
