First Claim
Patent Images
1. A metal complex having the formula:
-
space="preserve" listing-type="equation"> M(L.sub.1 L.sub.2 L.sub.3)!.sub.n - Y-X!.sub.mwhereinM is a divalent or trivalent metal cation selected from the group consisting of a rare earth metal cation and a transition metal cation;
L1, L2 and L3 are the same or different, and each is a ligand having at least two nitrogen-containing heterocyclic rings, wherein L1, L2 and L3 are bound to the metal cation via nitrogen atoms;
Y is a linker, connected to at least one of L1, L2 and L3, the linker containing at least one charge carrier independently selected from the group consisting of a positive charge carrier and a negative charge carrier;
X is a reactive functional group;
n is 1 to 10; and
m is 1 to 6.
