- wherein R1 to R16 are independently selected from the group consisting of;
- (A)hydrogen atom,
- (B)straight-chain, branched or cyclic saturated or unsaturated hydrocarbon groups having 1 to 50 of carbon atoms,
- (C)aryl groups substituted by at least one saturated or unsaturated hydrocarbon group having 1 to 50 of carbon atoms,
- (D)aryloxy groups substituted by at least one saturated or unsaturated hydrocarbon group having 1 to 50 of carbon atoms and
- (E)—O—R17, wherein R17 is selected from saturated or unsaturated hydrocarbon groups having 1 to 50 of carbon atoms;
- whereas at least one of R1 to R4, at least one of R5 to R8, at least one of R9 to R12 and at least one of R13 to R16 are selected from the group consisting of (B), (C), (D) and (E);
