报道了一系列含反式十氢萘环和两个由酯连接的芳环的液晶的合成和介晶行为。新化合物的结构经IR、~ 1H NMR、~（13）C NMR和元素分析确证。制备化合物18的单晶以确认十氢化萘环的反式构象。用差示扫描量热法和偏光显微镜研究了其液晶性质。所有的合成的化合物，除了17 E被发现，只有一个对映异构体的结晶相在一个很宽的温度范围内。
The synthesis and mesomorphic behaviour of a series of liquid crystals incorporating a trans‐decalin ring and two aromatic rings linked by esters are reported. Structures of the new compounds were confirmed by IR, 1H NMR, 13C NMR and elemental analysis. A single crystal of compound 18 was prepared to confirm the trans‐conformation of the decalin ring. Liquid crystalline properties were investigated by differential scanning calorimetry and polarising optical microscopy. All of the synthesised compounds except 17e are found to show only an enantiotropic nematic phase over a wide temperature range.
