Stabilization of the ScPhase in Mixtures of Laterally Aryl Substituted Mesogens

Autor: Wolfgang Weissflog, Gerhard Pelzl, C. Stützer, Siegmar Diele

Publikováno v: Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals. 317:181-195

Laterally 4-nitrobenzyloxycarbonyl substituted three-ring compounds preferably exhibit smectic A phases. However, induction of smectic C phases can be observed in binary mixtures with mesogens having a similar molecular shape but not a strongly polar

In Search of Smectic C Phases at Mesogens with a Phenyl Ring Containing Lateral Branch

Autor: C. Stützer, Wolfgang Weissflog

Publikováno v: Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals. 293:67-85

Generally, substituepts laterally attached at calamitic molecules prevent the existence of tilted smectic phases. However, mesogens with a bulky phenyl ring containing lateral branch are subjected to other relationships. The following constitutional

Helical twisting power of laterally aryl substituted chiral mesogens

Autor: C. Stützer, Wolfgang Weissflog, Horst Stegemeyer

Publikováno v: Liquid Crystals. 21:557-563

The relationship between the helical twisting power (HTP) of cholesteric liquid crystals and the molecular structure of the chiral mesogens has been investigated. Rod-like mesogens are compared with analogues bearing a bulky lateral branch. Additiona

Multiple dielectric relaxations in liquid crystals, their analysis and interpretation

Autor: C. Stützer, Horst Kresse, Wolfgang Weissflog, S. Tschierske, A. Hohmuth

Publikováno v: Liquid Crystals. 20:715-720

Dielectric measurements on laterally substituted molecules were carried out in the frequency range 10 Hz to 10 MHz. In these systems, the main part of the molecules exhibits only a very small dipole moment in the direction of the para-axis, whereas t

Novel Mesogenic Benzoic Acids with Large Branches I. Synthesis, Liquid Crystalline Properties and Crystal Structure Analyses of 3-(4-Subst.-benzyloxycarbonyl)-4-(4-n-octyloxybenzoyloxy) benzoic Acids

Autor: C. Stützer, Helmut Hartung, E. Dietzmann, F. Hoffmann, M. Drewello, Wolfgang Weissflog

Publikováno v: Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals. 275:75-90

New benzoyloxybenzoic acids bearing both terminal and lateral groups have been synthesized. Substituted aryl rings are laterally attached to the basic mesogens by means of an odd-numbered spacer. Therefore, liquid crystalline behaviour can be observe
