Abstract

Variable-temperature ¹H n.m.r. spectroscopic studies in CD ₃COCD₃ and u.v. spectroscopic measurements in Me ₂CO demonstrate that in the 1:1 complex, [Diquat·(1)] ²⁺, the guest is encapsulated within the host and that the complexation strength (ΔG^o = -7.4 kcal mol^-1) is enhanced by the macrobicyclic cryptate effect.
