The self-assembly of a complex with a [3]pseudorotaxane superstructure
Abstract
Dibenzo-24-crown-8, which contains two π-electron rich catechol units, self-assembles with the π-electron deficient 2,7-dimethyldiazapyrenium dication in solution to form a mixture of 1:1 and 2:1 complexes that have the ability to undergo further self-organisation on crystallisation to form linear arrays of [3]pseudorotaxanes between which diisopropyl ether molecules are trapped.
