摘 要:A new family of functionalized calix[4]arenes has been synthesized from calix[4]arene or azo-calix[4]arene by acylation with the corresponding co-alkylmercapto acid chloride. Six new compounds 4a-4e and 5a-5e were isolated and characterised by MALDI, elemental analyses, IH NMR and 13C NMR. NMR spectral data showed that these azo-functionalized calix[4]arenes 5a-5c are all in 1,3-alternate conformation in solution at room temperature while calix[4]arenes 4a-4e are all in cone conformation. The IR and UV properties of calix[4]arenes 5n-5e were also investigated.A new family of functionalized calix[4]arenes has been synthesized from calix[4]arene or azo-calix[4]arene by acylation with the corresponding co-alkylmercapto acid chloride.
