合成了一系列末端氰基的烷氧基和烷基氰基联苯化合物以及一些氰基对三联苯衍生物，并对其介晶性质进行了研究。与K系列和M系列的比较表明，末端氰基通常增强分子的过冷。此外，发现由氰基尾封端的化合物形成的几种二元LC混合物表现出与商业四元混合物E7相当的有前景的室温下的相范围。CN5OCB和CN7OCB的等摩尔二元混合物在金属盐修饰的表面显示垂直有序，在自由表面显示平面有序，这与我们计算的GBE值一致。因此，这些材料是显示对各种分析物的快速响应的传感器装置的有希望的候选者。
A series of cyano tail-terminated alkoxy and alkyl cyanobiphenyl compounds and some cyano-p-terphenyl derivatives were synthesized and mesogenic properties described. Comparison with the K series and M series indicates that the terminal cyano group generally enhances the supercooling of the molecules. Furthermore, several binary LC mixtures formed by the cyano tail-terminated compounds were found exhibiting promising room temperature nematic phases ranges comparable to the commercial quaternary mixture E7. The equimolar binary mixture of CN5OCB and CN7OCB shows homeotropic ordering at the metal salts-decorated surfaces and planar ordering at the free surface, which is consistent with GBEvalues we calculated. As such, these materials are promising candidates for sensor devices which display a rapid response to a variety of analytes.
