A 1:1 complex of [diquat] 2+ and a tailor‐made derivative of dibenzo[30]crown‐10 has been investigated in solution as well as in the solid phase. The crown ether is rigidified by an o ‐(CH 2 O) 2 C 6 H 4 bridge joining the two annelated benzene rings. Complicated exchange reactions in solution were studied NMR spectroscopically. X‐ray structure analyses have been carried out on the host molecule and the complex.
