Abstract:
The synthesis of a cyclohexa‐2,7‐(4,5‐diaryl)anthrylene ethynylene ( 1 ) was achieved for the first time by using 1,8‐diaryl‐3,6‐diborylanthracene and 1,8‐diaryl‐3,6‐diiodoanthracene as key synthetic intermediates. Macrocycle 1 possesses a planar conformation of approximately D 6 h symmetry, because of the triple‐bond linker between the anthracene units at the 2,7‐positions. It was confirmed that macrocycle 1 , bearing bulky substituents at the outer peripheral positions, behaves as a monomeric form in solution without π‐stacking self‐association. Macrocycle 1 has an inner‐cavity size that allows specific inclusion of [9]cycloparaphenylene ([9] CPP), but not [8]CPP or [10] CPP, through an aromatic edge‐to‐face CH‐π interaction.
