Abstract

Dynamic ¹ n.m.r. spectroscopy reveals that the disubstituted derivatives 2 - 4 of dibenzo-30-crown-10 (5) form strong 1:1 complexes in CD₃COCD₃ solution with the diquat dication. Desymmetrisation of the guest by the bound host provides the key to a novel application of this form of spectroscopic analysis to molecular receptor chemistry.
