α‐Octithiophene, the highest non‐substituted member of the α‐oligothiophene family known to date, has been obtained as razor‐blade thin, bright red single crystals shown between crossed polarizers on the cover of this issue. The synthesis, purification, crystal growth, and X‐ray analysis of the crystals are reported. The ratio of the a and c cell parameters is found to be exceptionally high ( a/c , is nearly 10), making α‐oligothiophene the record holder for structural anisotropy among organic crystals.
