    Abstract: The production of perylene-3,4-dicarboxylic acid imines of formula (I) (R is hydrogen, C1-C8 alkyl, C5-C8 cycloalkyl, possibly substituted phenyl or naphthyl; the radicals R are mutually independently hydrogen, C1-C18 alkyl, possibly substituted aryloxy, arylthio, hetaryloxy or hetarylthio), in which the corresponding perylene-3,4,9,10-tetracarboxylic acid or its anhydride (II) is reacted under pressure with an amide of formula (III) R -CO-NHR (R is C1-C4 alkyl or -NR R , in which R and R are mutually independently hydrogen or one of the alkyl, cycloalkyl, phenyl or naphthyl radicals R and where, if more than one of the radicals R , R and/or R is not hydrogen, these radicals have the same meaning) in the presence of an inert diluent and a transition metal catalyst.

    Abstract: Rylene derivatives of the general formula I in which the variables are each defined as follows: Rylene is a polycyclic conjugated ring system which comprises at least one perylene unit may comprise heteroatoms as ring atoms, may be functionalized by moieties comprising —CO— groups and/or may bear further substituents other than the A radicals; A is a radical of the formula X is oxygen or sulfur; R are identical or different radicals: optionally substituted alkyl, cycloalkyl, aryl, hetaryl, —U-aryl where U is an —O—, —S—, —NR2—, —CO—, —SO— or —SO2— moiety, or C1-C12-alkoxy, C1-C6-alkylthio, —C≡CR2, —CR2═CR22, hydroxy, mercapto, halogen, cyano, nitro, —NR3R4, —NR3COR4, —CONR3R4, —SO2NR3R4, —COOR3 or —SO3R3; R′ are identical or different radicals: hydrogen or one of the R radicals; R2 is hydrogen or alkyl, where the R2 radicals may be the same or different when they occur more than once; R3, R4 are each independently hydrogen; optionally substituted alkyl, aryl or hetaryl; n is from 1 to 8.

    Abstract: New mono- and bis-rylenedicarbimidyl-anthraquinone dyes (I) are claimed. New mono- and bis-rylenedicarbimidyl-anthraquinone dyes are of formula (I). R = H or (substituted) 1-30 C alkyl, 5-8 C cycloalkyl or (het)aryl; R' = Br, CN, -NR32 or (substituted) (het)aryloxy, (het)arylthio or 3-18 C alk-1-ynyl; R3 = H, 1-18 C alkyl or (substituted) (het)aryl; or NR32 = a 5-7-membered heterocyclic group; X, Y = H or together a 6-membered ring attached to a rylene ring system (Ia), in which X corresponds to the -NH- group and Y to the other free bond; n = 2, 3, 4 or may also be 1 if X and Y are a (Ia) group; and m = 0-6. The full definitions are given in the DEFINITIONS (Full Definitions) Field. Independent claims are also included for methods of preparing asymmetric (I; where X, Y = H) and symmetric and asymmetric (I, where X, Y = a 6-membered ring attached to arylene ring system).

    Abstract: A process for preparing terylene-3,4:11,12-tetracarboximides I where the variables are each defined as follows: R, R' are each independently hydrogen; if desired substituted alkyl or cycloalkyl; R 1 is hydrogen or alkyl; R 2 is hydrogen; alkyl; if desired substituted aryl or hetaryl, by reacting a perylene-3,4-dicarboximide II in the presence of a base-stable, high-boiling organic solvent and of an alkali metal or alkaline earth metal base, with a naphthalene-1,8-dicarboximide III in which X is hydrogen, bromine or chlorine.
