The present invention relates to the use of compounds 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)
both are each a —CWWM radical;
Y one of the two radicals is either a radical of the formula (y1)
-L-NR

(y1)
or a radical of the formula (y2)
-L-Z—R

(y2)
and the other radical is hydrogen;
are joined to one another with formation of a six-membered ring to give a radical of the formula (y3) or (y4)
or both are hydrogen;
W are each independently O or S;
W′ is O, S or N—R′,
with the proviso that at least one of the variables W or W in the general formula I is defined as S;
R, P, B, A, D, M, L, Z, R

and R′ are each defined as specified in the description;
m is 1, 2, 3 or 4;
n is 0, 2 or 4 when m=1, 2 or 3;
is 0, 2, 4 or 6 when m=4;
p is 0, 2 or 4 when m=1, 2 or 3, where n+p=0, 2 or 4;
is 0, 2, 4 or 6 when m=4, where n+p=0, 2, 4 or 6,
as active materials in solar cells or photodetectors.
The present invention further relates to the use of mixtures comprising, as components,
K1) compounds of the general formula (I) as electron donors or electron acceptors and
K2) one or more compounds which, with respect to component K1, act correspondingly as electron acceptors or electron donors
for producing photoactive layers for solar cells or photodetectors.
In addition, the present invention relates to the use of compounds of the general formula (I) as photosensitizers in solar cells or photodetectors.
Moreover, the present invention relates to solar cells and photodetectors which comprise compounds of the formula (I) or the aforementioned mixtures, and also to compounds of the general formula (I) and the aforementioned mixtures.
