A Self-Complexing
A supramolecular homodimer is formed in solution and in the solid state by a self-complementary [2]catenane incorporating a 1,5-dioxynaphthalene-based macrocyclic polyether interlocked with a bipyridinium-based tetracationic cyclophane (shown schematically). This unique example of self-recognition is the result of a combination of cooperative pi small middle dot small middle dot small middle dotpi and C-H small middle dot small middle dot small middle dotpi interactions.
