Thermotropic Liquid Crystals

Recent studies have reported a plethora of novel mesogenic molecules which triggered new interest in this area of research. As a result, a range of exciting molecules such as columnar liquid crystals that lack side chains, liquid crystalline dendrimers, and unusually shaped amphiphilic molecules have been made. Characterization of these surprising molecules poses a tremendous challenge to existing physical techniques. Thermotropic Liquid Crystals: Recent Advances covers developments in the field of thermotropic liquid crystals and and assesses their functional importance. In addition it presents advances related to different sub-areas pertinent to this interdisciplinary area of research. This comprehensive text has chapters covering the applications of high-resolution methods, such as solid-state NMR, that have been used to understand the high-resolution structure, dynamics, orientation, and orientational order of these molecules in various phases.

Will cover recent developments in the field of thermotropic liquid crystalline (LC) materials Design, characterization and applications of novel materials will be covered. For example, thiophene-based LCs, bent LC molecules, fullerene-based LCs, metallo mesogens, LC-polymers, LC networks (such as rubber laser, artifical muscles ) and biaxial thermotropics will be covered in detail New physical techniques that are powerful in characterizing these materials will also be covered. For example, multidimensional solid-state NMR techniques to determine the orientation order and structure of these molecules will be presented Will have chapters from various research labs that work on thermotropic liquid crystals Includes supplementary material: sn.pub/extras
