The Front Cover shows a striking pentagon‐shaped inflorescence of early blooms of Lantana camara overlaid by the unprecedented pentagonal array of stacks of corannulene (CORA) bowls in the structure of 1,3,5,7,9‐CORA(CF 3 ) 5 . Each stack is comprised of a gear‐like meshing of CF 3 groups with alternating chirality; molecules with C 5 symmetry lead to especially efficient bowl stacking. Ten new poly(trifluoromethyl)corannulenes with 3, 4, 5, 6, and 7 CF 3 groups represent the most thermodynamically stable isomers, which proves that the high‐temperature direct CF 3 I trifluoromethylation employed for their synthesis proceeds under thermodynamic control. The cover art was created by Ms. Audrey Mantooth. More information can be found in the Full Paper by I. V. Kuvychko, S. H. Strauss, A. A. Popov, O. V. Boltalina et al.
