Abstract:
Novel dithiopyrrolopyrrole derivatives having dichroic properties which have very high photostability in solution in a liquid-crystalline host are proposed.

Claim (Index 1):
A dithiopyrrolopyrrole compound of formula (1) in which\n R 1 , R 2 , R 3  and R 4 , independently of one another, stand for linear or branched, optionally halogen-substituted alkyl groups having 1 to 20 carbon atoms or halogen; \n Q 1  and Q 2  each denote single bonds or stand, independently of one another, for O, OCF 2 , CF 2 , CF 2 CF 2  or CO; \n A 1 , A 2 , A 3  and A 4  each denote single bonds or stand, independently of one another, for a group formed by phenylene, pyridine, pyrimidine, pyridazine, naphthylene, thiophene, selenophene and thiazole,\n with the proviso that \n (i) at least A 3  and A 4  must represent aromatic ring structures and \n (ii) the aromatic ring structures are optionally substituted by halide; and \n \n Z 1 , Z 2 , Z 3 , Z 4 , Z 5  and Z 6  each denote single bonds or stand, independently of one another, for a radical selected from the group formed by C\u2261C CH\u2550CH, CF\u2550CF, CF\u2550CH, CH 2 CH 2 , CF 2 \u2014CF 2  and CF 2 O, with the proviso that\n (iii) at least Z 3  and Z 4  represent either single bonds or a \u03c0-conjugated group.
