Patent ID: 8722879

Claim:
A compound of the general formula II: wherein M is a metal selected from the group consisting of Os, Ru, Fe, Cu, and Co; n is the formal oxidation state of the metal, wherein n is 0-4; X is a counter anion selected from the group consisting of Br − , Cl − , F − , I − , PF 6 − , BF 4 − , OH − ; ClO 4 − , SO 3 − , CF 3 COO − , CN − , alkylCOO − , arylCOO − , and any combination thereof; R 4 to R 27 is each independently selected from the group consisting of hydrogen, halogen, hydroxyl, azido, nitro, cyano, amino, substituted amino, thiol, C 1 -C 10 alkyl, cycloalkyl, heterocycloalkyl, haloalkyl, aryl, heteroaryl, alkoxy, alkenyl, alkynyl, carboxamido, substituted carboxamido, carboxyl, protected carboxyl, protected amino, sulfonyl, substituted aryl, substituted cycloalkyl, substituted heterocycloalkyl and group A, wherein at least one of said R 4 to R 27 is a group A: wherein A is linked to the ring structure of the compound of general formula II via R 3 ; R 3 is selected from the group consisting of cis/trans C═C, C≡C, N═N, C═N, N═C, C—N, N—C, alkylene, arylene and any combination thereof; R 2 is selected from the group consisting of alkyl, alkylene, aryl, arylene and any combination thereof; R 1 is absent or is selected from the group consisting of hydrogen, trialkoxysilane, trihalidesilane, thiol, COOH, COO − , Si(OH) 3 and phosphonate; and any two vicinal R 4 -R 27 substituents, together with the carbon atoms to which they are attached, may form a fused ring system selected from the group consisting of cycloalkyl, heterocycloalkyl, heteroaryl and aryl, wherein said fused system may be substituted by one or more groups selected from the group consisting of C 1 -C 10 alkyl, aryl, azido, cycloalkyl, halogen, heterocycloalkyl, alkoxy, hydroxyl, haloalkyl, heteroaryl, alkenyl, alkynyl, nitro, cyano, amino, substituted amino, carboxamido, substituted carboxamido, carboxyl, protected carboxyl, protected amino, thiol, sulfonyl and substituted aryl; and said fused ring system may also contain at least one heteroatom selected from the group consisting of N, O and S; and m is the number of A groups.
