POLYMERIZABLE CHIRAL COMPOUNDS CONTAINING 2,6-NAPHTHYL- AND ISOMANNITE 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.
