Abstract:
1. An active material in solar cells or photodetectors comprising a compound of the general formula (I) in which the variables are each defined as follows: X are joined to one another with formation of a six-membered ring to give a radical of the formula (x1), (x2) or (x3)  or both are each a —CWWM radical; Y one of the two radicals is either a radical of the formula (y1)  or a radical of the formula (y2)  and the other radical is hydrogen; or both are hydrogen; W are each independently O or S; W′ is O, S or N—R′, R are identical or different radicals: P is an amino radical —NR B is C A is —COOM, —SO D is 1,2-phenylene, 1,2- or 2,3-naphthylene or 2,3- or 3,4-pyridylene, each of which may be mono- or polysubstituted by C M is hydrogen, an alkali metal cation or [NR L is a chemical bond or an arylene or hetarylene radical which is bonded to the rylene skeleton directly or via ethenylene or ethynylene and is of the formulae  in which the (het)arylene radicals Ar may be the same or different, may comprise heteroatoms as ring atoms and/or may comprise fused saturated or unsaturated 5- to 7-membered rings which may likewise comprise heteroatoms, where the entire ring system may be mono- or polysubstituted by phenyl, C E is a chemical bond or an —O—, —S—, —NR R Z is —O— or —S—; R R′ is hydrogen; R R R R m is 2, 3 or 4; n is 0, 2 or 4 when m=2 or 3; p is 0, 2 or 4 when m=2 or 3, where n+p=0, 2 or 4;
