| Abstract: | This paper presents an efficient synthetic procedure of 2, 7-diethoxycarbonyl-3, 6, 10, 11-tetrabutoxytriphenylene starting from pyrocatechol. The chemical structures of the materials are characterized by using 1HNMR and Fourier transform infrared spectroscopy; the materials properties are characterized by differential scanning calorimeter and polarized optical microscopy. 2,7-diethoxycarbonyl-3,6,10,11 -tetrabu- toxytriphenylene displays columnar plastic crystalline phase at the temperature range from 152 to 196.9℃. |
