Synthesis and Mesophase Behaviour of Morpholinium Ionic Liquid Crystals

“…Among the known ILC, imidazolium or pyridinium salts are the mostly studied compounds. 14,15 Besides, some functional groups, such as aromatic cores, 16,17 alkyl-chains with different lengths and natures, 18 lateral substitution groups, 19,20 metal-containing groups, 21 and counteranions, 22,24 have been extensively studied for the preparation of mesogenic compounds. Only a few thermotropic ionic liquid crystals based on other cations have been reported.…”

Supramolecular Structures in the Presence of Ionic Liquids

“…As for imidazolium ILs with long alkyl chains (C n ≥ C 12 ), liquid crystal (LC) phase often appears in the course of increasing temperature (Bowlas et al, 1996;Bradley et al, 2002;De Roche et al, 2003;Getsis & Mudring, 2008;Holbrey & Seddon, 1999;Lee et al, 2000;Lee et al, 1997;Li et al, 2005b;Zhou & Antonietti, 2004). If an anion has a long alkyl chain, the long alkyl chains on the imidazolium ring are not necessary for the formation of LC .…”

“…In the former, the ionic head groups interact with the counterions through Coulomb force, while the latter build from (anti)parallel stacking of the alkyl chains through van der Waals force. Moreover, the hydrogen bonds between the H-atoms of imidazolium cations and anions are important in the formation and stabilization of ionic layers (Lee et al, 2000;Lee et al, 2004;Lee et al, 1997). The functionalization of imidazolium is a useful method for the application of imidazolium ionic LCs.…”
