Abstract

Single crystals and thin films of the p-type organic semiconductor alpha,omega-dihexylquaterthiophene have been studied using X-ray diffraction and TEM, respectively. The single crystal analysis reveals the presence of monomolecular layers of quaterthiophene cores with terminally bound hexyl chains. A herringbone molecular packing akin to that exhibited by the parent quaterthiophene molecule is observed. Electron diffraction of thin films on silica clearly shows the crystalline polymorph of the solution-grown crystals and the crystallites deposited by organic molecular beam deposition are identical. However, thin film crystallites are severely affected by multiple twinning.
