series of oxaazacyclophanes and oxaazacalix[4]areneanalogues with 18-, 20- and 22-membered rings have been synthesized from diamine and dialdehyde building blocks and structurally characterized by spectroscopic methods. One diamine precursor and four macrocycles have additionally been analysed by single-crystal X-ray diffraction. Two of the oxaazacalix[4]areneanalogues were employed for metal ion complexation
