摘要
The synthesis and mesomorphic properties of new triazole liquid-crystalline are presented and discussed. These triazole derivatives have been synthesized by reacting 4-hydrazoic iodobenzene with the 4-alkyl phenyl acetylene in dimethyl formamide (DMF). The molecular structure is characterized by 1H NMR, Fourier transform infrared spectroscopy (FTIR), time-of-flight mass spectrometry (TOF-MS) and the mesomorphic properties are characterized by polarizing optical microscope (POM) and (DSC). These new triazole liquid-crystallines have higher melting point and clearing point and the final compounds display both nematic and smectic liquid-crystalline phases.
