Claim:
A compound of formula (I) where R 0 is a substituted or an unsubstituted C 1 to C 4 alkyl group, R 1 is selected from the group consisting of: H, N(R 7′ R 7″ ), a substituted C 1 to C 4 alkyl group, an unsubstituted C 1 to C 4 alkyl group, and CN, R 2 or R 2′ are selected from the group consisting of: H, a substituted C 1 to C 4 alkyl group, an unsubstituted C 1 to C 4 alkyl group, and a group with the formula [(CR 8 R 8′ )—(CR 9 R 9′ ) m —(CR 10 R 10′ ) n —(CR 11 R 11′ ) o ]—NR 12 R 12′ wherein m, n and o are 1 or 0, R 8 , R 8′ , R 9 , R 9′ , R 10 , R 10′ , R 11 or R 11′ are independently selected from the group consisting of: H, a substituted C 1 to C 4 alkyl group, and or an unsubstituted C 1 to C 4 alkyl group; and R 12 or R 12′ are independently selected from the group consisting of: H, a substituted C 1 to C 4 alkyl group, and an unsubstituted C 1 to C 4 alkyl group, R 3 is selected from the group consisting of: H, a substituted C 1 to C 4 alkyl group, an unsubstituted C 1 to C 4 alkyl group, a substituted C 1 to C 4 alkoxy group, and an unsubstituted C 1 to C 4 alkoxy group, R 4 is selected from the group consisting of: H, a substituted C 1 to C 4 alkyl group, an unsubstituted C 1 to C 4 alkyl group, a substituted C 1 to C 4 alkoxy group, and an unsubstituted C 1 to C 4 alkoxy group, R 5 is selected from the group consisting of: H, substituted C 1 to C 9 alkyl group, and an unsubstituted C 1 to C 9 alkyl group, wherein the C 1 to C 9 alkyl group is a branched or linear C 1 to C 9 alkyl group, R 6 is selected from the group consisting of: a substituted C 1 to C 9 alkyl group, an unsubstituted C 1 to C 9 alkyl group, an unsubstituted aryl group, and a substituted aryl group, wherein the C 1 to C 9 alkyl group is a branched or linear C 1 to C 9 alkyl group, wherein the sum of carbon atoms of R 5 and R 6 is at least 4 carbon atoms, R 7′ or R 7″ are independently selected from the group consisting of: a substituted C 1 to C 4 alkyl group, an unsubstituted C 1 to C 4 alkyl group, and R 7′ and R 7″ form together with the nitrogen atom a five or six membered aromatic or a five or six membered cyclo alipahatic, wherein the five or six membered rings are substituted by a C 1 to C 4 alkyl group or the five or six membered rings are not further substituted.
