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.
