Series of semi-fluorinated chain liquid crystals with [1,2,3]-triazole rings have been synthesized with CuI-Et_3N catalyzed alkyne-azide cycloaddition reaction. The selectively produced 1,4-disubstituted regioisomers were characterized by using IR, NMR, and Mass. The mesomorphic behaviors were characterized with polarizing optical microscopy and differential scanning calorimetry. Compounds with perfluorinated chains have showed smectic A phase.
