Popis:	The title compds. I (n = 3, 11) were prepd. utilizing the Stetter reaction followed by ring closure with Lawesson's reagent. Optical studies and cond. data of doped I together with a series of differently sized oligothiophenes show that at the chain length of 11 thiophene rings the properties closely resemble those of polythiophene. Hence, the min. effective conjugation length in polythiophenes is proposed to be approx. 11 thiophene units. [on SciFinder (R)]
