The palladium-catalyzed Sonogasira coupling reaction was used as the key step to synthesize the amphiphilic Volano-Bola amphiphilic compounds. The structure of the product was confirmed by 1H NMR, 13C NMR and elemental analysis. The POM and DSC methods were used to investigate the liquid crystal behavior The results show that this compound is a column-type thermotropic liquid crystal.The ultraviolet spectrum of the compound confirms that the π-π stacking form of the V-type aromatic nuclei in the assembly model is an H-aggregated structure, and the UV- (ahν) 2 The calculated energy gap range The compounds can be used as semiconductor materials, fluorescence spectroscopy to infer that they can be used as a potential Blu-ray material, a larger Stokes shift value of the compound indicates that the compound in the laser material and fluorescent photon radiation meter Etc. In addition, the results of Gaussian computational simulation show that the compound is nearly ideal planar conjugate structure.
