![]() each independently and independently on each occurrence are a radical selected from the following groups:
a) the group consisting of 1,4-phenylene, 1,4-naphthylene, 2,6-naphthylene, tetralin-5,8-diyl, and tetralin-2,6-diyl, in which one or two CH groups may be replaced by N and in which one or more H atoms may be replaced by L,
b) the group consisting of trans-1,4-cyclohexylene, 1,4-cyclohexenylene, bicyclo[1.1.1]pentane-1,3-diyl, 4,4′-bicyclohexylene, bicyclo[2.2.2]octane-1,4-diyl, and spiro [3.3]heptane-2,6-diyl, in which one or more non-adjacent CH2 groups may be replaced by —O— and/or —S— and in which one or more H atoms may be replaced by F or alkyl having 1 to 6 C atoms,
c) the group consisting of thiophene-2,5-diyl, thieno [3,2-b]thiophene-2,5-diyl, and selenophene-2,5-diyl, each of which may also be mono-or polysubstituted by L,
