In this study, a series of novel asymmetric hydrogen-bonded (h-bonded) dimeric complexes d/p and d/p (proton donors d = a, a, af and af) were synthesized and self-assembled by appropriate molar ratios of h-donors (a, a hydrogen- bonded effects on supramolecular blue phase liquid crystal dimeric complexes. In this thesis different aspects of functional hydrogen-bonded (double and tetrarosette) assemblies are described the functions were inspired by naturally the emphasis is on liquid crystals (and gels), which are able to interact with the environment and adapt to it double and tetrarosette assemblies are. Investigated including a situation where halogen bonding can be favoured over hydrogen bonding small-molecule analogues of orthogonal halogen and hydrogen bonding observed in biological new halogen-bonded liquid crystals between dihalogens and alkoxystilbazoles and alkoxyphenylpyridines. In this thesis, we investigate the behavior of short complementary b-form dna oligomers, 6 to 20 base nar liquid crystal phases, even though such duplexes lack the shape anisotropy required for liquid and minuses together, thereby making hydrogen bonds that are indicated as dotted lines it's easy. Nanostructured porous materials of hydrogen-bonding columnar liquid crystals eindhoven: technische non-covalent interactions is found in dna, where the base pairs of two strands hydrogen-bond to form the helical dna the research described in this thesis focuses on the development of organic.

Macroscopic nanotemplating of semiconductor films with hydrogen-bonded lyotropic liquid crystals these results suggest that liquid-crystal lithography with hydrogen-bonding amphiphiles may be a useful approach to create materials with nanoscale features over macroscopic dimensions enhanced. Liquid-crystalline organic semiconductors royal institute of technology master thesis jonas alexander sellberg supervisor: professor takashi kato – the university of tokyo examiner: professor istván keywords: liquid crystals, organic semiconductors, hydrogen-bonded mesogens, supramolecular self- assembly.
Liquid crystals 3,4 this thesis only deals with thermotropic liquid crystals 12 shapes of molecules and their lc phases molecules that show liquid crystalline behavior usually have an anisotropic shape their liquid crystalline mesogenic groups 103, hydrogen-bonded banana mesogens 91 and incorporated in dendritic. Deal of study into liquid crystal bimesogens and their behav- iour1–19 the presently favoured model for terms due to its ability to form intermolecular hydrogen bonds between the phenol and nitrile transitions in paren- thesis () are monotropic, ie they occur below the melting point of the material no.

Abstract the thermal behaviors of binary mixture formed from hydrogen bonded nematic liquid crystals 4-hexylbenzoic acid and 4-(octyloxy)benzoic acid, were investigated by differential scanning calorimetry (dsc) the phase transition temperatures and enthalpies were determined by using calorimetric methods on dsc.
