1,6,9,14-teltrasubstituted terrylene tetracarboxylic diimides

摘要

The invention relates to 1,6,9,14-tetrasubstituted terrylene tetracarboxylic acid diimides of general formula (I), in which the variables are defined as follows: X, Y independently of one another represent bromium; cyano; aryloxy, arylthio, hetaryloxy or hetarylthio, which can respectively be mono- or polysubstituted by C₁-C₁₂ alkyl, C₁-C₁₂ alkoxy, -COOR¹, -SO₃R¹, halogen, hydroxy, carboxy, cyano, -CONHR² and/or -NHCOR²; a group of formula -L-R³; a group of formula -NR²₂; R, R' independently of one another represent hydrogen; C₁-C₃₀ alkyl, whose carbon chain can be interrupted by one or more groupings -O-, -S-, -NR₁-, -CO- and/or -SO₂- and which can be mono- or polysubstituted by cyano, C₁-C₆ alkoxy, aryl, which may be substituted by C₁-C₁₈ alkyl or C₁-C₆ alkoxy and/or a 5- to 7-membered heterocyclic group that is bonded by means of a nitrogen atom and that can contain additional heteroatoms and be aromatic; C₅-C₈ cycloalkyl, whose carbon skeleton can be interrupted by one or more groupings -O-, -S- and/or -NR¹- and/or which can be mono- or polysubstituted by C₁-C₆ alkyl; aryl or hetaryl, which can be mono- or polysubstituted by C₁-C₁₈ alkyl, C₁-C₆ alkoxy, cyano, -CONHR², -NHCOR² and/or aryl- or hetarylazo, which can be respectively substituted by C₁-C₁₀ alkyl, C₁-C₆ alkoxy or cyano; and L represents 1,2-ethylene, 1,2-ethenylene or 1,2-ethynylene.
