通过Mitsunobu反应合成了一系列具有一个或三个手性软链的新型手性三苯基盘状液晶。手性盘状液晶的产率可达84%。化学结构经1H NMR确证；用偏光显微镜和差示扫描量热法研究了其亚形态。介形研究表明：①手性盘原具有六方柱状或塑性柱状介相；2)引入手性可以降低三苯基盘状液晶的熔点，从而扩大中间相范围。此外，还观察到一个意想不到的奇偶效应。
A series of new chiral triphenylene-based discotic liquid crystals with one or three chiral soft chains were synthesized through Mitsunobu reactions. Yields of the chiral discotic liquid crystals were achieved up to 84%. Chemical structures were confirmed by 1H NMR; and mesomorphism was studied by polarized optical microscopy as well as by differential scanning calorimetry. The mesomorphic studies have shown that 1) the chiral discogens have either hexagonal columnar or plastic columnar mesophases; and 2) the introduction of chirality to triphenylene-based discotic liquid crystals could widen mesophase range by lowering melting points. In addition, an unexpected odd-even effect of mesomorphism was observed.
