    • The invention concerns compounds of general formula (I) Z-Y-A-(Y-M)n-Y -X-Y -(M-Y)n-A-Y-Z in which the groups A, independently of one another, are spacers, n is 1, 2 or 3, X is a group of formula (a), (b), (c), (d), (e), (f), (g) or (h), the groups Y , independently of one another, designate O, OCO, OCOO, or a direct bond, the groups Y, independently of one another, designate O, S, CO, COO, OCO, OCOO, CONR, NRCO or a direct bond, R is hydrogen or a C1-C4 alkyl, the groups M, independently of one another, designate an aliphatic, aromatic, heteroaliphatic or heteroaromatic ring system optionally substituted by chlorine, bromine, fluorine, iodine, cyan or methyl, and the groups Z, independently of one another, designate hydrogen or a polymerizable group. These compounds are suitable for use in electro-optical display elements, as chiral doping substances for nematic or cholesteric liquid crystals for producing coloured reflective layers or pigments disposed cholesterically by liquid crystals.
    • 本发明涉及通式(I)ZYA(YM)N <1> -X-Y <1>的化合物 - (MY)nAYZ,其中基团的A独立地彼此间隔,n是1,2或3,X是一个基团 式(a),(b),(C),(D),(E),(F),(g)或(h)中,基团Y <1>独立地为O,OCO,OCOO或直接 键,该基团Y彼此独立地为O,S,CO,COO,OCO,OCOO,CONR,NRCO,或直接键,R是氢或C1-C4烷基,基团M独立,任选地被氯,溴,氟取代的 碘,氰基或甲基取代的,脂族,芳族,杂脂族或杂芳族环体系,基团Z各自独立地为氢或可聚合基团。 新化合物是适用于电光学显示元件的使用,作为用于产生反映在颜色或用于液晶胆甾醇排序颜料的制备层向列型或胆甾型液晶的手性掺杂剂。
