Formation of sandwich, macrocyclic and box supramolecular assemblies that were controlled by the distance of two oxygen atoms in hydrogen bonding donors

Abstract

Sandwich 12·2, macrocyclic 1·3 and box 12·42 supramolecular assemblies were synthesized by the reaction of 1,8-bis(4-pyridylethynyl)anthracene 1 with hydroquinone 2, resorcinol 3 and 1,5-dihydroxynaphthalene 4via hydrogen-bonding interactions, respectively. The formed sandwiches, macrocycles and boxes can further self assemble to form a double-layer supramolecular polymer, nanotubes and a one-dimensional “iron chain type” supramolecular polymer. Investigation of their crystal structures revealed that the distance between two oxygen atoms in a hydrogen bonding donor play an important role in the formation of supramolecular assemblies.
