The flexibility of the additional sidechains of 4TICO allows the material to reorganise itself upon annealing, leading to higher solar cell performance.

Establishing the rather complex correlation between structure and charge transfer in organicorganic heterostructures is of utmost importance for organic electronics and requires spatially resolved structural, chemical and electronic details. Insight in this issue is provided here by combining atomic force microscopy, Kelvin probe force microscopy, photoemission electron microscopy and low-energy electron microscopy for investigating a case study. We select the interface formed by pentacene (PEN), benchmark among the donor organic semiconductors, and a p-type dopant from the family of fluorinated fullerenes. As for Buckminsterfullerene (C60), the 2 growth of its fluorinated derivative C60F48 is influenced by thickness and crystallinity of the PEN buffer layer, but the behaviour is markedly different. We provide a microscopic description of the C60F48/PEN interface formation and analyse the consequences in the electronic properties of the final heterostructure. For just one single layer of PEN, a laterally complete but non-compact C60F48/PEN interface is created, importantly affecting the surface work function. Nonetheless, from the very beginning of the second layer formation, the presence of epitaxial and non-epitaxial PEN domains dramatically influences the growth dynamics and extremely well packed twodimensional C60F48 islands develop. Insightful element maps of the C60F48/PEN surface spatially resolve the non-uniform distribution of the dopant molecules, which leads to a heterogeneous work function landscape.

Two derivatives of [1]benzothieno[3,2-b][1]benzothiophene (BTBT), namely, 2,7-dioctyl-BTBT (C8-BTBT) and 2,7-diphenyl-BTBT (DPh-BTBT), belonging to one of the best performing organic semiconductor (OSC) families, have been employed to investigate the influence of the substitutional side groups on the properties of the interface created when they are in contact with dopant molecules. As a molecular p-dopant, the fluorinated fullerene C 60 F 48 is used because of its adequate electronic levels and its bulky molecular structure. Despite the dissimilarity introduced by the OSC film termination, dopant thin films grown on top adopt the same (111)-oriented FCC crystalline structure in the two cases. However, the early stage distribution of the dopant on each OSC film surface is dramatically influenced by the group side, leading to distinct host−dopant interfacial morphologies that strongly affect the nanoscale local work function. In this context, Kelvin probe force microscopy and photoelectron emission spectroscopy provide a comprehensive picture of the interfacial electronic properties. The extent of charge transfer and energy level alignment between OSCs and dopant are debated in light of the differences in the ionization potential of the OSC in the films, the interface nanomorphology, and the electronic coupling with the substrate.
