Paper Abstract

The results of original investigations being in touch with regularities of the chiral components molecular structure effect on the properties of induced cholesteric mesophases were generalized. It was shown that presence of an elongate (pi) -electron fragment in the chiral dopants molecules is general requirement of high helical twisting power ((beta) ). (beta) values and the character of temperature dependences of induced helical pitch are significantly effected by molecular shape of chiral dopants. Variation of the extent of (pi) -electron fragment anisometry, and also incorporation and variation of terminal alkyl or alkoxyl groups at chiral dopants molecules are useful approach to a regulation of temperature dependences of induced cholesteric helix pitch. Influence on thermal stability of mesophases of different types of chiral dopants was analyzed.
