Development of novel chiral dopants to be used in ferroelectric liquid crystal system

The study of chiral dopant and its application in liquid crystal system is one of the largest area of research in fluids leading to technological application in the field of display devices. Chiral dopant when mixed with achiral host mixture forms ferroelectric liquid crystal to be used in surface stabilised liquid crystal devices. 4-(pentyl, heptyl, nonyl)-2, 3 difluoro terphenyl nitriles and (S)-(-)-1-cyno-2-methylbutyl-4-pentyl-difluoroterphenyl- 4′-carboxylate were synthesised and mixed with achiral host mixture HM1 with the percentage of 3 and 7. Ferroelectric properties of synthesised FLC 1 were studied.

The Synthesis of Optically Active Cyanohydrin Esters and Their Use as High Ps Dopants for Ferroelectric Displays

This paper describes the reasoning underlying the design and synthesis of a range of cyanohydrin esters, specifically as high Ps dopants of host SC materials, for use in fast switching ferroelectric displays.Full synthetic details are given for the preparation of optically pure cyanohydrin esters from naturally occuring L-amino-acids; examples derived from (a) a D-amino-acid, (b) lactic acid are also given.Such materials provide excellent dopants which in suitable SC hosts provide mixtures with wide S*C ranges, good Ps values and long pitches, which switch rapidly at room temperature and may be multiplexed at video frame rates. - Keywords: ferroelectric materials, high Ps dopants, chiral cyanohydrin esters.
