Claim:
A compound having the structure (R) i (L) j or (R) i (L) j (M) k (F) l (N(R′) p ) q or (R) i (L) j (M) k (F) l (W) q wherein R is selected from the group consisting of the following structures R2 to R4: and wherein L is selected from the group consisting of the following structures L1 to L3, L5 to L10, and L12 to L15: wherein: M is a metal atom having a valence of +2 or greater; i is an integer from 1 to 4; j is an integer from 1 to 4; k is an integer from 1 to 4; l is an integer from 1 to 4; F is one or more fluoride atoms; N is a nitrogen atom; W or N(R′) p is a counter-ion that maintains the neutrality of the compound; wherein W is selected from the group consisting of hydrogen, an alkali metal ion, and ammonium; and wherein N(R′) p is selected from the group consisting of C 1 to C 50 substituted or unsubstituted quaternary ammonium ions, and C 1 to C 50 substituted or unsubstituted pyridinium ions; each R′ is a substituted or unsubstituted aliphatic or aromatic group comprising 1 to 50 carbon atoms, wherein at least one of the R′ groups comprises at least one polymerizable group; and wherein the various R′ groups can be the same or different; and wherein p is an integer from 1 to 4; q is an integer from 0 to 4; a dotted line represents the position of a bond between R and L; X is an ether —O— linkage or an —NH— linkage; and the various X moieties may be the same or different; Z 1 is hydrogen or a substituted or unsubstituted alkyl group comprising 1 to 4 carbon atoms; and the various Z 1 moieties may be the same or different; Z 2 is hydrogen, fluoride, or a substituted or unsubstituted alkyl group comprising 1 to 4 carbon atoms; and the various Z 2 moieties may be the same or different; n is an integer from 0 to 6; and the various values for the parameter n may be the same or different; and m is an integer from 0 to 6; and the various values for the parameter m may be the same or different.
