Abstract
Cyclobis(paraquat-o-phenylene) cyclophane can be synthesised in the form of a free radical within the gallery space of a synthetic aluminosilicate cla y mineral. The interlayer formation of the cyclophane was revealed by XRD, IR and optical measurements. The mechanism of its formation is consistent w ith a one electron redox synthesis in which the electron donated by the cla y mineral plays the role of the template towards the pi -electron deficient bipyridinium moieties.
