Herein we report general methods allowing the synthesis of various perfluoroalkylated corannulenes with a specific substitution pattern. Variable temperature NMR spectroscopic investigations revealed dynamic behavior which was analyzed by line shape analysis. The activation parameters of these dynamic processes were determined. For a tetrasubstituted compound it was possible to observe through space

Aromatic diimides are one of the most important chromophores in the construction of n‐type organicsemiconductors, which lag far behind their p‐type counterpart but are necessary for ambipolar transistors, p‐n junctions and organic complementary circuits. Herein, we establish a facile one‐pot domino synthetic protocol for aromatic diimides via palladium‐catalyzed carbonylation of tetrabromo aromatic

oxidation of exo-cyclic sulfur atoms enhances the molecular reduction potential of non-planar polycyclic aromatichydrocarbons and allows for a systematic bridging of the electron affinity gap between corannulene, a fragment of fullerene C60, and the prevalent fullerene-based electron acceptor phenyl-C61-butyric acid methyl ester (PCBM).

Herein, we explore the synthesis of corannulene‐based ribbon‐shaped molecules through a repetitive Diels–Alder strategy. For this, appropriate corannulene‐based dienes and dienophiles were identified and synthesized. These building blocks could be combined in a modular way to obtain the dimeric and trimeric segments of the hypothetical molecularribbons. 1D and 2D NMR measurements, along with crystal‐structure
