Abstract : The synthesis of 1,4-disubstituted-[1,2,3]-triazoles involving the addition of aryl azide to terminal acetylenes andethyl acetoacetate are employed in the preparation of a series of non-linear mesogens having ester and imine as linking units. The structures of final compounds and their intermediates are characterized by FTIR, 1HNMR and 13CNMR spectroscopy. Optical microscopy and differential scanning calorimetry confirm structural information of liquid crystal phases of mesogens. The final compounds reveal preferentially well-defined threaded nematic phases. In addition, they show weak fluorescence in solution with poor quantum yields and a Stokes shift of around 70 nm.
