The invention relates to compounds of the formula (I)
in which Y
1
and Y
2
are each O or, respectively, NR
a
or NR
b
, where R
a
and R
b
are each H or organyl; Z
1
to Z
4
are each O or S; R
11
to R
14
, R
21
to R
24
are each Cl, F; where 1 or 2 of the R
11
to R
14
, R
21
to R
24
radicals may also be CN and/or 1 R
11
to R
14
, R
21
to R
24
radical may be H; and where, when Y
1
is NR
a
, Z
1
or Z
2
may also be NR
c
, where R
a
and R
c
together are a bridging X group having from 2 to 5 atoms; and where, when Y
2
is NR
b
, Z
3
or Z
4
may also be NR
d
, where R
b
and R
d
together are a bridging X group having from 2 to 5 atoms;
to a process for preparation thereof, and to their use as emitter materials, charge transport materials or exciton transport materials.
