ABSTRACT
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 scalar coupling. The packing motifs were elucidated by X-ray crystallography, showing that the substitution pattern as well as the size of substituents strongly influence intermolecular π-stacking. The reduction potentials of the perfluoroalkylated compounds were determined by cyclic voltammetry.
