other donors 9,10-bis(4-pyridinylethynyl)anthracene (L3) and 1,4-di(4-pyridinylethynyl)buta-1,3-diyne (L4) resulted in [2]catenane 5 and non-catenane ring-in-ring topological macrocycle 7 respectively. Rectangular macrocycles 2, 4, 6, and 8 were respectively obtained when the self-assembly of acceptor A with one of the donors L1–L4 was carried out under dilute conditions in nitromethane or methanol.
