Abstract

Abstract A series of tetrahedral oligothiophenes bearing n-hexyl groups at the α-positions of the terminal thiophene rings,(nC 6 H 13 (C 4 H 2 S) n) 4 C (Hex-TnTM; n= 1–4), has been synthesized by Kosugi–Migita–Stille coupling as a key reaction. Thanks to the improved solubility afforded by the terminal n-hexyl groups, the largest homologue (n= 4) was successfully obtained. Whereas the smaller derivatives (n= 1, 2) were obtained as liquid ...
