Abstract

A new donor–acceptor [2]catenane incorporating one 3,5-bis(methylene)-1H-1,2,4-triazole unit and one 1,5-dioxynaphthalene unit in the macrocyclic polyether component undergoes spontaneous resolution upon crystallisation, providing evidence that the inclusion of this triazole unit in the neutral component favours the phenomenon.
