Organic Molecular Beam Deposition of Highly Oriented β‐Tetrahexylsexithiophene Films

Abstract

Organic molecular beam deposition (OMBD) enables the fabrication of organic materials with controlled and reproducible electronic and optical properties. For electronic and photonic applications of organic materials, poly- and oligothiophenes are among the most interesting. Here the growth of highly oriented films of β-tetrahexylsexithiophene by OMBD onto an organic ionic crystal substrate is reported. Analysis of UV-vis absorption spectra demonstrates a clear relationship between the ordered structure of the film and the crystal lattice of the substrate.
