摘要
A series of oxaazacyclophanes and oxaazacalix[4]arene analogues 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]arene analogues were employed for metal ion complexation studies based on UV/Vis absorption spectroscopy, showing both compounds to be able to form complexes with Cu2(+) and Zn2(+).
