摘　　要： 本研究采用邻苯二酚、溴代正戊烷和乙酰氯为原料合成了以苯并菲为基元的盘状液晶化合物2,6,10-三乙酯基-3,7,11-三戊氧基苯并菲,化合物的结构采用核磁手段1HNMR进行鉴定。采用偏光显微镜POM和DSC手段对该种化合物的相行为进行了研究,并且与合成过程中的中间体2,3,6,7,10,11-六戊氧基苯并菲的相行为进行了比较。 A triphenylene-based discotic liquid crystal compound 2, 6, 10-tricarbetboxy-3, 7, 11-tripentyloxytriphenylene was synthesized using 1-Bromopentane, Catechol and Acetyl chloride raw materials. The structure of the compound was determined by 1 HNMR spectrum. The phase behaviors of 2, 6, 10-tricarbetboxy-3, 7, 11-tripentyloxytriphenylene and 2, 3, 6, 7, 10, 11-hexapentloxytriphenylene were determined by DSC and POM methods. The results showed that the range of liquid crystal of 2, 3, 6, 7, 10, 11-hexapentloxytriphenylene is much wider than that of 2, 6, 10-tricarbetboxy- 3, 7, ll-tripentyloxytriphenylene and phase transition temperature of 2, 3, 6, 7, 10,11-hexapentloxytriphenylene is much lower than that of 2, 6, 10-tricarbetboxy-3, 7, 11-tripentyloxytriphenylene.
