Study of chirality in liquid crystals is one of the most interesting areas of liquid crystal science. Liquid crystallineterphenyls with two lateral fluoro substituent and alkyl substituent in the 4- have been synthesised. Convergentapproach was appli... Read More

Cyanoalkyl difluoro-terphenyl-carboxylate chiral dopants (2012)
Journal Article
Kayani, Z. N., Naseem, S., & Lewis, R. A. (2012). Cyanoalkyl difluoro-terphenyl-carboxylate chiral dopants. Journal of Molecular Liquids, 170, (11-19). doi:10.1016/j.molliq.2012.03.018. ISSN 0167-7322

A liquid crystal like difluoroterphenyl chiral dopant was synthesized to match the dimensions of a host chiral dopant mixture. The melting point of the chiral dopants was decreased by increasing the length of the alkyl chain. The melting point of the... Read More

The influence of an alkenyl terminal group on the mesomorphic behavior and electro-optic properties of fluorinated terphenyl liquid crystals (2010)
Journal Article
Hird, M., & Lewis, R. (2010). The influence of an alkenyl terminal group on the mesomorphic behavior and electro-optic properties of fluorinated terphenyl liquid crystals. Journal of materials chemistry, 20(2), 299 - 307. doi:10.1039/b914260f

Novel liquid crystal terphenyls with two, three and four lateral fluoro substituents and an alkene unit at the end of a terminal chain are presented in terms of synthesis, mesomorphic behaviour and electro-optic properties. The difluoro analogues wer... Read More

Molecular complexity and the control of self-organising processes (2009)
Journal Article
Goodby, J. W., Saez, I. M., Cowling, S. J., Gasowska, J. S., MacDonald, R. A., Sia, S., …Vaschenko, V. (2009). Molecular complexity and the control of self-organising processes. Liquid crystals, 36(6-7), 567-605. doi:10.1080/02678290903146060

In this article we investigate the complexity of the molecular architectures of liquid crystals based on rod-like mesogens. Starting from simple monomeric systems founded on fluoroterphenyls, we first examine the effects of aromatic core structure on... Read More
