New pyrrolo: or thieno:perylene-imide compounds

摘要

Pyrroloperylene or thienoperylene imide compounds of formula (I) are new. A = NR2 or S; R3 = H, or may also be NHP(O)(OEt)2 or NEt2 if A = NH; R1, R2 = (i) H; (ii) isocyclic aryl, preferably with 1-4 (especially 1 or 2) rings, such as phenyl, biphenylyl or naphthyl; or (iii) heteroaryl preferably with 1-3 rings (optionally including fused benzene rings), such as pyridyl, pyrimidyl, pyrazinyl, triazinyl, furanyl, pyrrolyl, thiophenyl, quinolyl, isoquinolyl, coumarinyl, benzofuranyl, benzimidazolyl, benzoxazolyl, dibenzofuranyl, benzothiophenyl, dibenzothiophenyl, indolyl, carbazolyl, pyrazolyl, imidazolyl, oxazolyl, isoxazolyl, thiazolyl, indazolyl, benzothiazolyl or pyridazinyl, cinnolyl, quinazolyl, quinoxalyl; groups (ii) and (iii) are optionally substituted by non-water solubilising groups.
