The present invention relates to a process for preparing fused tetrahydro-[
1
H]-triazoles of the formula I
1
where the variables R
a
, Z, Z
1
, X, W, n and Q are as defined in claim 1, by cyclization of compounds of the formula II
2
where R is C(X)OR
2
or C(X)SR
2
, where X is oxygen or sulfur, and R
2
is as defined in claim 1, in the presence of a base.
The invention also relates to compounds of the formula I where W is sulfur if Z is a methylene group optionally substituted by R
a
, and furthermore to compounds of the formula I where Q is a benzoxazole or benzothiazole radical, and to the use of these compounds as herbicides.
A mesogenic, crosslinkable mixture comprising at least one polymerisable liquid crystal and at least one polymerisable dichroic dye of the general formula I:
wherein
Arepresents a dichroic residue exhibiting at least partial absorption in the visible region > 400 nm;
n1, n2, n3, n4signifies 0 or 1 whereby the sum of n1, n2, n3 and n4 is >0, and
B1 to B4represent a group of substructure II
wherein the broken line symbolises the linkage to said dichroic residue.
