Communication: alpha-Octithiophene, the highest non-substituted member of the alpha-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 alpha-oligothiophene the record holder for structural anisotropy among organic crystals.
