Abstract
A tetraazaperopyrene compound of formula (I): wherein: R1, R2, R3, R4, R5, R6, R7, R8 at each occurrence, independently are selected from H, Cl and Br, with the proviso that at least one of R 1, R2, R3, R4, R5, R6, Wand R8 is Cl or Br, R9, R10, at each occurrence, independently are selected from H, a C1-30 alkyl group, a C1-30 haloalkyl group, a C6-14 aryl group, a heteroaryl group having 5 to 14 ringatoms, and a C7-20 arylalkyl group, wherein aryl, heteroaryl and arylalkyl can be optionally substituted with one or more halogen, C1-4 haloalkyl, —CN, —NO2, —CHO, —COOH, —CONH2, —CO(C1-14 alkyl), —COO(C1-14 alkyl), —CONHC(C1-14 alkyl) and —CON(C1-14 alkyl)2 groups.
