    Abstract: The use of chiral, uncharged metal compounds containing two tridentate ligands with mesogenic groups, spacer groups and other groups as dopants for liquid crystalline materials. The use of chiral, uncharged compounds of formula (Ia) or (Ib) as dopants for liquid crystalline (LC) materials. ((P -Y -A -Y M -Y -)nL)2Me (Ia) ((P -Y -A -Y -M -Y -)nL)Me(L'(-Y -M -Y -A -Y -P )n')m (Ib) P , P = H, 1-12C alkyl, polymerizable groups, groups suitable for polymerization, or residues bearing such polymerizable groups; Y -Y = single bonds, -O-, -S-, -CO-, -COO-, -OCO-, -CONR-, -NRCO-, -OCOO-, -OCONR-, -NRCOO- or -NRCONR-; R = H or 1-4C alkyl; A , A = 1-30C spacer groups; M , M = mesogenic groups; n, n' = 0 or 1; m = 1, 2 or 3; Me = a transition metal of Period 4, 5 or 6 (other than technetium, silver, cadmium, gold, mercury or lanthanides) or a Main Group 14 element (other than carbon or lead); L = a tridentate ligand of formula (II); U, V, W = nitrogen-, phosphorus- or sulfur-containing groups with N, O, P or S atoms with free electron pair(s) for coordination with the central metal atom (Me); b1, b2 = 2-3C alkylene bridges attached to U and V or V and W, optionally substituted with up to two 1-12C organic residues in the case of 2C bridges and up to 4 such residues in other cases, and in which 2 adjacent carbon atoms may form part of an optionally substituted, optionally anellated benzene ring; L' = a 1-12C organic group. The groups L'(Y -M -Y -A -Y -P )n' in formula (Ib) may be different. Independent claims are also included for the following: (1) New compounds of formula (IIIa) and (IIIb). (2) LC materials containing compound(s) (Ia) and/or (Ib) or (IIIa) and/or (IIIb). ((P -Y -A -Y M -Y -)L)2Me (IIIa) ((P -Y -A -Y -M -Y -)L)Me(L'(-Y -M -Y -A -Y -P )n')m (IIIb) n' = 0 or 1.

    Abstract: New liquid crystalline mixtures comprise: (a) difunctional mesogenic compound(s) (I); (b) reactive compound(s);and (c) optionally additives. New liquid crystalline mixtures comprise: (a) at least one difunctional mesogenic compound of formula Z1-Y1-A1-Y3-M-Y4-A2-Y2-Z2 (I); (b) at least one reactive compound selected from (i) vinyl or allyl ethers, (ii) vinyl or allyl esters of (un)saturated carboxylic acids, (iii) (meth)acrylate esters of mono- or polyfunctional alcohols, (iv) polyester (meth)acrylates, (v) vinyl (hetero)aromatic compounds, and (vi) N-vinyl amide or amine compounds of formula CH2=CH-NR1R2 (II); and (c) optionally further additives. Z1, Z2 = reactive groups (preferably photopolymerizable groups); Y1 - Y4 = direct bond, O, S, OC(O), OC(O)O, C(O)NR, NRC(O), OC(O)NR, NRC(O)O or NRC(O)NR; R = H or 1-4C alkyl; A1, A2 = 1-30C spacers, in which the carbon chains are optionally substituted by one or more Me, F, Cl or Br and interrupted by one or more O, S or non-adjacent NH or N(1-4C alkyl); M = mesogenic group; R1, R2 = -C(O)R3 or R3; R2, R3 = H or 1-4C alkyl; R2 + R3 = optionally unsaturated 3-5C alkylene (in which 1 or 2 CH2 groups are optionally replaced by NH, N(1-4C alkyl), N(6-10C aryl) or O and 1 or 2 CH group are optionally replaced by N).
