Ultrathin films of functionalized oligomers with well‐defined chain and conjugation lengths are of interest for organic electronic devices. Using the example of end‐capped quinquethiophene vapor‐deposited onto a Ag(111) surface, it is demonstrated that highly ordered monolayers of chemisorbed oligomers can be obtained in very large defect‐free domains. LEED and STM (see Figure) studies provide information about the geometric parameters, molecular structure, and quality of the layers.
