Induction of liquid-crystallinity in molecular clips by binding of different guest molecules
Van Nunen, Johanna L. M.,Nolte, Roeland J. M.
, p. 1473 - 1478 (1997)
The use of clip molecules based on diphenyl- and dimethyl-glycoluril as building blocks for liquid-crystalline materials is described. The synthesis is performed by an esterification of hydroxy-derived clip molecules with trialkoxybenzoyl chloride. 1
"not quenched" aggregates of a triphenylene derivative for the sensitive detection of trinitrotoluene in aqueous medium
Arora, Harshveer,Pramanik, Subhamay,Kumar, Manoj,Bhalla, Vandana
, p. 3187 - 3193 (2016)
Triphenylene derivative 4 bearing gallic acid groups at the periphery has been synthesized. Derivative 4 formed "not quenched" porous aggregates in mixed aqueous medium. These aggregates served as potent chemosensors for the selective detection of trinitr

Tristriazolotriazines (TTTs) with a threefold alkoxyphenyl substitution were prepared and studied by DSC, polarized optical microscopy (POM) and X-ray scattering. Six pentyloxy chains are sufficient to induce liquid-crystalline behavior in these star-shap
Spontaneous Mirror-Symmetry Breaking in Isotropic Liquid Phases of Photoisomerizable Achiral Molecules
Alaasar, Mohamed,Prehm, Marko,Cao, Yu,Liu, Feng,Tschierske, Carsten
supporting information, p. 312 - 316 (2016/01/25)
Spontaneous mirror-symmetry breaking is of fundamental importance in science as it contributes to the development of chiral superstructures and new materials and has a major impact on the discussion around the emergence of uniform chirality in biological
Structure-property relationship in charge transporting behaviour of room temperature liquid crystalline perylenebisimides
Prajitha,Chithiravel,Krishnamoorthy,Asha
, p. 9882 - 9891 (2015/02/05)
A homologous series of pentadecyl phenol functionalized perylenebisimide (PBI) terminated with trialkoxy gallate esters was synthesized, where the terminal alkyl chain length was varied from n = 4 to 12 (PBI-En). The thermotropic liquid crystalline (LC) c
Effect of central linkages on mesophase behavior of imidazolium-based rod-like ionic liquid crystals
Cheng, Xiaohong,Su, Fawu,Huang, Rong,Gao, Hongfei,Prehm, Marko,Tschierske, Carsten
scheme or table, p. 2274 - 2285 (2012/06/30)
Two series of phenylbenzylether and benzanilide based rod-like imidazolium bromides and their nonionic precursors, the 1-phenyl-1H-imidazoles have been synthesized and the influence of the number and length of the alkyl chain(s) and the structure of the linking group in the aromatic core (-CH2O-, -COO-, -CONH-) on their mesophase self-assembly in ionic liquid crystalline phases were studied by POM, DSC and XRD. Upon decreasing the length of the N-terminal chain or by enlarging the number and length of the C-terminal chains, the sequence smectic (SmA)-hexagonal columnar (Colhex)-micellar cubic (CubI/Pm3n) was found for the ether based imidazolium salts; while only SmA and Colhex phases were observed for the related amides. The influence of the polarity of the central linkages, namely -CH 2O- and -CONH-, on the mesophase structure and stability is discussed and compared with related -COO- connected ILC.

The synthesis and structural analysis of a polymer containing twin- dendritic benzamide side-groups (i.e. poly{N-[3,4-bis(n-dodecan-1-yloxy)- 5(1-methacryloyl-η-undecan-1-yloxy)phenyl]-3,4,5-tris(n-dodecan-1- yloxy)benzamide}) (19) are described. The disc

A new type of disc-shaped molecule (1a-c) has been synthesised and characterised. The molecules were built up by linking three lipophilic, N-monoacylated 2,2'-bipyridine-3,3'-diamine wedges to a central 1,3,5-benzenetricarbonyl unit. They show liquid crys
