Novel calixarene analogues having Schiff base units have been synthesised by condensation reaction of the bisaldehyde with o-phenylenediamines in the presence of boric acid. The present calixarene analogues form hydrogen bonds between imine nitrogen and phenol hydrogen with 1,2-alternate conformation, confirmed by X-ray crystallography.
