POLYMERIZABLE CHIRAL COMPOUNDS COMPRISING 2,6-NAPHTHYL AND ISOMANNITOL UNITS, AND USE THEREOF AS CHIRAL DOPANTS

摘要

The present invention relates to compounds of the general formula I; in which the variables are each defined as follows: W is a (Y⁴-T²-)_s(Y³-A²-)_tY²—Z² moiety, Z¹, Z² are each independently unreactive radicals as defined more specifically in the description or reactive radicals through which polymerization can be brought about, A¹, A² are each independently spacers as defined more specifically in the description, Y¹ to Y⁵ are linking units as defined more specifically in the description, Y⁶ is a chemical single bond or —CO—, T¹, T² are each independently, as defined more specifically in the description, divalent saturated or unsaturated, optionally substituted and optionally fused iso- or heterocyclic radicals, Q is substituents as defined more specifically in the description, r, t are each independently 0 or 1, s is 0, 1, 2 or 3 and q is 0, 1, 2, 3 or 4. ;The invention further relates to a liquid-crystalline composition which comprises at least one compound of the formula I, and to the use of the compounds of the formula I as chiral dopants.
