Synthesis of rod-like bis-ester liquid crystals and their influence on photoelectric properties of liquid crystalline materials
摘要:
Six novel rod-like magnetic liquid crystals have been prepared, in which trans-bicyclohexyl or trans-cyclohexylphenyl and biphenylcarboxylic acid phenyl ester mesogenic cores with n-propyl and n-pentyl substituents were terminated by 4-hydroxyl-TEMPO (TEMPO=2,2,6,6-tetramethylpiperidine-1-oxy). Their structures were confirmed by elemental analysis, IR and MS.Determined by SQUID, EPR, DSC and HS-POM (heat stage polarizing optical microscope), the six compounds all have both magnetic and liquid crystalline properties; their temperature ranges of mesophase were from 16.0 to 24.8℃, and the magnetic liquid crystal molecules could obviously improve the response sensitivity of liquid crystal materials.
