Easily Accessible Thermotropic Hydrogen‐Bonded Columnar Discotic Liquid Crystals from Fatty Acid– Tris‐Benzoimidazolyl Benzene Complexes
We report the formation of easily accessible hydrogen-bonded columnar discotic liquid crystals (LCs) based on tris-benzoimidazolyl benzene (TBIB) and commercially available fatty acids. By increasing the length of the fatty acid, the temperature range of liquid crystallinity was tuned. Introducing double bonds in octadecanoic acid lowered the crystallization temperature and increased the temper...
متن کاملNew SmCG phases in a hydrogen-bonded bent-core liquid crystal featuring a branched siloxane terminal group.
In this study, we synthesized three analogous bent-core molecules, a hydrogen-bonded complex and a covalent-bonded compound with branched siloxane units (H-SiO and C-SiO, respectively) and a hydrogen-bonded complex with an alkyl unit (H-Alk), and investigated the effects of the hydrogen bonding and branched siloxane terminal units on their mesomorphic properties. The covalent-bonded compound C-...
متن کاملDetermination of Thermo Optical Parameters Using Image Analysis Technique in nBA: 7HB Hydrogen Bonded Liquid Crystals
ABSTRACT: In this paper, thermo optical properties of homologous series of hydrogen bonded liquid crystals: p-n alkyl benzoic acid (nBA): heptyl p hydroxybenzoate (7HB) (where n=5 to 10) have been investigated by means of applying Image analysis technique in conjunction with Polarizing Optical Microscope. Textures of liquid crystal complexes are captured. The changes in textural features as a f...
متن کاملTerahertz Vibrations and Hydrogen-Bonded Networks in Crystals
The development of terahertz technology in the last few decades has made it possible to obtain a clear terahertz (THz) spectrum. THz vibrations clearly show the formation of weak bonds in crystals. The simultaneous progress in the code of first-principles calculations treating noncovalent interactions has established the position of THz spectroscopy as a powerful tool for detecting the weak bon...
متن کاملProton Transfers in Hydrogen Bonded Organic Crystals at Low Temperatures
The tunneling dynamics of protons involved in hydrogen bonds between carboxylic acid dimers is determined using picosecond transient grating techniques.
