Abstract

Disclosed are compounds of formula V wherein M is selected from: a metal atom; a metal compound; 2H whereby one H is bonded to each of the two nitrogen atoms depicted as being bonded to M (positions 29 and 31 shown) R3 is H or methyl; R1 and R4 are independently selected from: H, C1 to C4 alkyl, C2 to C4 alkenyl, methoxy, butoxy, propoxy, NH2, NH—(C1 to C4 alkyl), N—(C1 to C4 alkyl)2, S—(C1 to C4 alkyl); R8 to R25 are the same or different and are independently selected from: C1 to C32 alkyl; C2 to C32 alkenyl; X—O—Y; X—phenyl, X2COOX1, X2CONR1R11, H; halide; wherein: X and X2 are independently selected from: a chemical bond, —(CH2)n— wherein n is an integer from 1 to 32, —(CH2)a—CH═CH(CH2)b where a and b are independently selected from integers 0-32 and a+b totals 32; X1 and Y are independently selected from: C1 to C32 alkyl, C2 to C32 alkenyl, and H; R1 and R11 are independently selected from: H; C1 to C32 alkyl, C2 to C32 alkenyl, —(CH2)n—; with the proviso that at least one of R8 to R25 is selected from: C1 to C32 alkyl, C2 to C32 alkenyl, X—O—Y, X—phenyl, X2COOX1, X2CONR1 R11.
