Abstract：An intermediate, 4,4′-［4,6-bis(hexyloxy)-1,3-phenylene］bis｛1-［4-(azidomethyl)benzyl］- 1H-1,2,3-triazole｝(6), was prepared by a five-step reaction from resorcinol. 1,2,3-Triazolophane(7) was obtained by Click reaction of 6 with 1,5-diethynyl-2,4-bis(hexyloxy)benzene under pseudo-high dilution conditions. A novel tetramethylated 1,2,3-triazolium-phane was synthesized by the reaction of trimethyloxonium tetrafluoroborate with 7. The structure was characterized by 1H NMR， 13C NMR and HR-ESI-MS.
