New Orthoconic Antiferroelectrics Useful for Applications

Abstract

Molecular structures and their relation to the mesogenic behavior as well as physical parameters of orthoconic antiferroelectric smectic phases formed by partially fluorinated esters are reviewed. New multicomponent mixtures with long pitch and their electrooptical performance are demonstrated.

Keywords:

• orthoconic antiferrolectric
• phase-transition structure relation
• smectic layer property
• tilt
• electrooptical performance
• long helical pitch mixture
