The monoaza derivatives of crown ethers form complexes with primaryalkylammonium thiocyanates analogous to those formed by the crown ethers. The n.m.r. spectra of the complexes show temperature dependence which can be analysed in terms of various types of guest exchange processes and conformational changes of the host molecules. In particular, rapid conformational changes of the host macrocycle, accompanied
