摘要
Alkylated terrylenes can be synthesized by a twofold cyclization of an appropriately substituted trinaphthyl[1,11]. In this paper, we consider a special case. The alkyl substitution in the starting material 1 strongly affects the interplanar angle between the naphthalene moieties. After cyclization, the substituents are positioned in the sterically crowded bay region of the title structure 2. The influence of the steric strain on the reactivity of 1 and on the stability of the resulting hydrocarbon 2 is investigated. Special emphasis is placed on the crystal structures of 1 and 2.
