The Cover Feature shows how the out‐of‐plane cyclic ketal substituents on a hexaazatrinaphthylene derivative overcome steric crowding to undergo long‐range self‐assembly by first forming a dimer, which then forms spherulites by long‐range self‐organization involving an interlocking pairwise inverse packing. This process can be compared with the “burr puzzle” (a traditional Chinese toy), whereby the pieces having both mortises and tenons accurately interlock to form a 3D structure. The assembly of the interlocking pieces requires patience and dexterity, and resembles the time‐consuming formation of spherulite growth. More information can be found in the Full Paper by C. W. Ong and co‐workers (DOI: 10.1002/cplu.201900593).
