Synthesis and NMR, UV–VIS, electrochemical, mobility and X-ray characterization of 3,3″″′-bis(butylsulfanyl)-2,2′∶5′,2″∶5″,2‴∶5‴,2″″∶5″″,2″″′-sexithiophene are reported. This compound combines the promising properties already observed for 3,3‴,3″″′-tris(butylsulfanyl)-2,2′∶5′,2″∶5∶,2‴∶5‴,2″″∶5″″,2″″′-sexithiophene with a physical state more suitable for its use in field-effect transistors. In particular
3,3″″′-双(丁基硫烷基)-2,2′∶5′,2″ ∶5″,2‴∶5‴,2的合成及NMR,UV-VIS,电化学,迁移率和X射线表征报道了“″ ∶5″″,2″″′-二噻吩。该化合物结合了3,3‴,3″'''-三(丁基硫烷基)-2,2′∶5′,2″ ∶5∶,2‴∶5‴,2″″ ∶5″的已观察到的有希望的性质具有更适合在场效应晶体管中使用的物理状态的“,2”“'-亚硒基噻吩。特别地,氧化形式的稳定性,固态的紧密堆积以及所观察到的迁移率和开/关比使得该六噻吩对于有机半导体具有潜在的兴趣。
