Abstract Two calix[4]arene derivatives containing 1,2,3-triazole moiety were synthesized via K2CO3-catalyzed 1,3-dipolar cycloaddition reaction between calix[4]arene-based azide and active methylene compounds in good yields. The structures of the two compounds synthesized herein were fully confirmed by 1H NMR, 13C NMR, and MS (ESI). The thermal analysis showed that the mass losses of the synthesized compounds 4 and 5 containing 1,2,3-triazole groups are similar to each other.
