Book excerpt: Liquid crystals (LCs) show unique optical and physical properties, and so these compounds are attractive for many applications, including displays, sensors, reconfigurable mirrors, photonic devices, etc. [1-5]. Due to the cost and performance limitations of devices based on existing LC materials, it is essential to develop novel systems that are cost-effective and with enhanced performance. Also, it is crucial to explore the properties of these soft matter materials with respect to the molecular modifications to better understand their broad applicability. This is especially the case if the phase types involved are recently discovered. Many chiral dopants required for cholesteric preparations are either obtained from conventional chemical synthesis or from plant extracts. So, in search for novel dopants which are of biological origin and are relatively cheaper to produce in large volume, a study has been carried out to develop chiral compounds made from the fermentation derived bio-precursors. Likewise, the recently discovered nematic ferroelectric (NF) LCs [6] have not yet gained practical utility though they have potential to be applied in next generation displays and optoelectronic devices. Although these NF LCs show response towards ultra-small driving voltage ~1V/cm [7], the realistic applications are limited due to their current shortcomings such as monotropic LC phase, high temperature phase transition, thermochemical instability, etc. Thus, to develop novel improved systems and to seek their pragmatic applications, a variety of unique NF LCs have been synthesized and studied. Similarly, to explore the synthetic challenges and the properties related to their structural features, several classic compounds such as cyanobiphenyls (CBs), CB dimers, and triphenylene discotics have been prepared and examined.

Available in PDF, EPUB and Kindle. Book excerpt: Liquid crystals have found wide applications due to their unique properties. In order to search for new nematic liquid crystal compounds with relatively low phase transition temperatures, a series of [1,2,3]-triazole-based mesogens and LC dimers were synthesized via the "Click Reaction" under mild conditions and their phase behavior will be presented. Meanwhile, hydrogen-bonded complexes mixed by benzonitrile derivatives and aromatic acetylenes are obtained and their thermal behavior examined. In order to achieve a better understanding of the influence of difluorination on the oligophenyls, a series of partially fluorinated oligomers were obtained and some of their physical properties are compared. Organic semiconductors possess many advantages compared to conventional inorganic semiconductors. Perfluorination was utilized in our molecular design for the synthesis of 1,3,5-triphenyl benzene derivatives and self-assembled crystals via nitrogen-iodine halogen bonding and the target molecules might show some interesting semicondocting properties.
