摘要
A novel biscalixarene with two kinds of calix[4]arene derivative units connected by four bridging chains, was facilely＇ synthesized by ＂1 ＋ 1＂ condensation mode in high yield. The element analyses, ESI-MS, ^1H NMR and ^1H-^1H COSY spectrum showed that the calix[4]arene units of compound 4 were in cone conformations and compound 4 possessed biscalixarene-tube structure. 2007 Fa Fu Yang.
