Liquid crystalline guanidinium phenylalkoxybenzoates: towards room temperature liquid crystals via bending of the mesogenic core and the use of triflate counter ions
TL;DR: A series of guanidinium salts 1(C n ) m m −4 (C n m m ǫ X bearing phenyl alkoxybenzoate cores have been synthesized and their mesomorphic properties have been investigated by polarising optical microscopy (POM), differential scanning calorimetry (DSC) and powder X-ray diffraction experiments as mentioned in this paper.
Journal ArticleDOI
Headgroups versus symmetry in congruent ion pairs: which one does the job in mesomorphic aryl guanidinium and aryl imidazolium sulphonates?
Martin Butschies,Markus Mansueto,Johannes Christian Haenle,Christof Schneck,Stefan Tussetschläger,Frank Giesselmann,Sabine Laschat +6 more
TL;DR: In this article, the effect of the number and symmetry of lipophilic side chains and the type of head group on the phase type and thermal mesophase properties was probed by the synthesis and investigation of two series of novel guanidinium and imidazolium sulphonates and compared with the corresponding iodides.
Journal ArticleDOI
Induction of ionic smectic C phases: a systematic study of alkyl-linked guanidinium-based liquid crystals
TL;DR: A series of ionic liquid crystals with an alkoxy biphenyl unit tethered via an alkyl spacer to a guanidinium head group were synthesized and the mesomorphic properties were studied by differential scanning calorimetry, polarising optical microscopy and X-ray diffraction (XRD; WAXS and SAXS).
Journal ArticleDOI
Dendrimeric triphenylbenzenes: helical versus zig-zag arrangement in columnar mesophases
TL;DR: In this article, a small series of dendrimers consisting of a star-shaped triphenylbenzene core unit and bulky lateral groups was synthesized and their mesomorphic properties were investigated via differential scan.
