PAb11 アキラルバナナ型分子液晶相からのSHGの観察

抄録

Several liquid crystalline phases of the achiral bent-shaped molecules have been investigated by optical second harmonic generation (SHG). A difference in the SHG activities between compounds with alkyl and alkoxy end chains have been already pointed out. Whereas, it has been reported that the texture and domain size were affected by cooling rate. We observed the cooling rate dependant SHG behavior in the thermodynamic phases of several bent-shaped molecules, and discussed the cooling and the end chain effects.
