Structure-properties relationships in liquid crystal thiols
Cseh, Liliana,Mehl, Georg
, p. 879 - 885 (2014/08/18)
Two new series of thiols were studied in order to establish the structure-properties relationships. First series consists of compounds with three or four aromatic rings as rigid part of mesogen and the second contains thiols with a flexible chain attached
Structure-property relationships in non-chiral liquid crystal oligomers stabilizing blue phases
Iwamochi, Hirotoshi,Yoshizawa, Atsushi
experimental part, p. 223 - 232 (2011/08/10)
We prepared 4-(4-cyanophenyl)phenyl 4-octyloxybenzoate derivatives possessing a laterally attached mesogen and investigated their phase transition behavior. They showed a wide temperature range of a nematic phase in spite of being far from a rod-like stru
Synthesis of crescent aromatic oligoamides
Yuan, Lihua,Sanford, Adam R.,Feng, Wen,Zhang, Aimin,Zhu, Jin,Zeng, Huaqiang,Yamato, Kazuhiro,Li, Minfeng,Ferguson, Joseph S.,Gong, Bing
, p. 10660 - 10669 (2007/10/03)
This article describes the synthetic procedures for the preparation of crescent (and helical) aromatic oligoamides developed in recent years in our laboratory. The large-scale preparation of a variety of monomers derived from various tetrasubstituted benzenes is presented. Three different strategies for constructing various oligomers consisting of meta- and meta/para-linked benzene residues are discussed. Factors affecting coupling efficiency and yields are analyzed. The developed synthetic methods have provided the basis for the preparation of longer oligomers and for the development of solid-phase synthesis.
Nematic silsesquioxanes - Towards nanocrystals dispersed in a nematic liquid crystal matrix
Elsaesser, Ralf,Mehl, Georg H.,Goodby, John W.,Photinos, Demetri J.
, p. 851 - 852 (2007/10/03)
The reaction of suitable organic groups in combination with well defined inorganic silsequioxane cores leads to covalently bound organic-inorganic hybrid materials, which exhibit nematic and smectic C phase behaviour close to room temperature.

The Coordinative Behaviour of N-Substituted 2-(Δ2-Imidazolin-2-yl)-phenols as Metal Extractants
Beger, J.,Wagner, G.,Dinjus, U.,Goerls, H.,Uhlig, E.,Sieler, J.
, p. 211 - 224 (2007/10/02)
N-Substituted 2-(Δ2-imidazolin-2-yl)-phenols (R4NNOH) are obtained by the reaction of N-alkyl diaminoethane-1,2 and 2-hydroxybenzoic acid esters.In contrast to many other copper(II) complexes with the donor set N2O22- (A),
O- and N-Alkylsubstituted 2-(2'-Hydroxyphenyl)-benzimidazoles and -1,3,4-Oxadiazoles as Complexing and Extracting Agents for Copper-II-Ions
Beger, J.,Wagner, G.,Uhlig, E.,Dinjus, U.
, p. 708 - 718 (2007/10/02)
2-(2'-Alkoxyphenyl)-benzimidazoles 1, 1-alkyl-2-(2'-hydroxyphenyl)-benzimidazoles 2, 2-(2'-hydroxy-4'-alkoxyphenyl)-benzimidazoles 3, 2-(2',4'-dialkoxyphenyl)-benzimidazoles 4 and 1-alkyl-2-(2'-hydroxy-5'-nitrophenyl)-benzimidazoles 7 are synthesized by condensation of 2-hydroxybenzoic acid derivatives and o-phenylendiamine or its derivatives.Alkyl chains (C4, C8 or C12) are introduced by alkylation before or after the ring closure in order to increase the solubility of the reagent in toluene or n-octane.Furthermore the extraction properties of the benzimidazoles are investigated.Also some new analogous compounds of the benzothiazole and the 1,3,4-oxadiazole series were synthesized.
