The present invention provides a compound comprising a repeating unit of formula (I)
in which:
Arepresents a nitrogen atom, a carbon atom, a group -CR1- or an aromatic or alicyclic group, wherein R1 represents a hydrogen atom or lower alkyl,
Mrepresents a repeating monomer unit;
n1 to n3each independently represent 0 or an integer having a value of from 1 to 3, with the proviso that 1 < n1 + n2 + n3 < 4;
P1, P2, P3each independently represent a photoactive group; and
B1 to B4each independently represent a residue of general formula II
as well as photoactive polymers prepared from such compounds and the use of such compounds in the preparation of liquid crystal orientation layers and structured and unstructured electro-optical elements.
