Rational Monomer Design towards 2D Polymers: Synthesis of a Macrocycle with Three 1,8‐Anthrylene Units

Abstract

An iterative synthesis of a macrocycle with three 1,8-anthrylene units (see picture, R=C6H13) was achieved by using Pd-catalyzed cross-coupling protocols, in which a copper-free Sonogashira reaction was the key to the final cyclization. Photochemical model reactions suggest that the macrocycle has the potential to undergo photo-induced [4+4] cycloaddition without undesired side reactions, which is of relevance for the ultimate goal of creating 2D polymers.
