Design and rheological behaviour of lactic acid based cholesteric liquid crystalline materials with hydroquinone unit in the molecular core

Popis výsledku v původním jazyce

In order to contribute to molecular structure – physical property relationship for chiral self-assembling materials, chiral compounds derived from the lactic acid have been designed. The materials, contain three phenyl rings connected by the ester linkage groups and two flexible alkyl chains, the hydroquinone unit was used in the molecular core, different lengths of the chiral alkyl chain were used. The mesomorphic properties were established by POM and DSC. The rheological characterization was performed in the cholesteric phase which exhibits a slight electrorheological effect, at low shear rates, that continuously decrease with the increase of the shear rate, due to the competition of the flow and electric fields. Quite broad temperature range of the cholesteric phase down to room temperature makes studied LCs as suitable chiral dopants for design of new multicomponent mixtures targeted for various applications in photonics and optoelectronics.
