The fabrication of a green‐and red‐emitting pixel structure (see figure, scale bar 10 μm) by the single‐step, surface‐tension‐driven assembly of a single luminescent thiophene‐based molecular material is reported. The solid‐state organization of the selected thiophene‐based oligomer is controlled by exploiting the molecular structural arrangement, induced during a dewetting process and facilitated by the great conformational flexibility of the oligomer, typical of several substituted oligothiophenes.
