| Synthese und ferroelektrische Eigenschaften chiraler Ester von 2,5-Diphenylpyrimidinen mit a-Fluorcarbonsäuren Synthesis and Ferroelectric Properties of 2,5-Diphenylpyrimidines with Different a-Fluorocarboxylic Acids  | | | | Abstract
| Chiral esters of 2-[4-/?-hexylphenyl]-5-[4-hydroxyphenyl]pyrimidine and 2-[4-w-hexyloxy-phenyl]-5-[4-hydroxyphenyl]pyrimidine with four different a-fluorocarboxylic acids have been synthesized. The spontaneous polarization and the tilt angles in the smectic C* phase were m easured as a function of tem perature. All compounds exhibit wide range smectic C* phases, the highest values of the spontaneous polarization being about 400 nC/cm: . Additionally the spon taneous polarization in a higher ordered smectic phase was determ ined, the values ranging up to about 600 nC/cm2. The spontaneous polarization/tilt angle ratio strongly increases with decreasing tem perature. | | | |
