Abstract:
The invention relates to rylene derivatives of general formula (I) in which the variables have the following meanings: rylene contains a polycyclic conjugated ring system, which contains at least one perylene unit (formula II), can contain heteroatoms as ring atoms, can be functionalized by groupings containing CO- groups and/or can carry other substituents different from radicals A; A represents a radical of formula (III); X represents oxygen or sulfur; R represents the same or different radicals: optionally substituted alkyl, cycloalkyl, aryl, hetaryl, -U-aryl, U representing a grouping -O-, -S-, -NR2-, -CO-, -SO- or -SO2-, or C1-C12 alkoxy, C1-C6 alkylthio, -C=CR2, -CR2=CR22, hydroxy, mercapto, halogen, cyano, nitro, -NR3R4, -NR3COR4, -CONR3R4, -SO2NR3R4, -COOR3 or -SO3R3; R1 represents the same or different radicals; hydrogen or one of the radicals R; R2 represents hydrogen or alkyl, radicals R2 being able to be the same or different when repeatedly occurring; R3 and R4, independent of one another, represent hydrogen, optionally, substituted alkyl, aryl or hetaryl, and; n represents 1 to 8.
Abstract:
The present invention relates to a cyanated perylene compound of the formula (I) in which one of the Z substituents and one of the Z* substituents are cyano and the other Z substituent and the other Z* substituent are each independently CO 2 R 9 , CONR 10 R 11 , optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl or C 6 -C 14 -aryl, where R 9 , R 10 and R 11 are each as defined in the claims; and mixtures thereof. The present invention further relates to a composition comprising a cyanated perylene compound of the formula (I) or mixtures thereof and to a process for preparation thereof; to color converters comprising at least one polymer as matrix material and at least one cyanated perylene compound or mixtures thereof or a composition comprising at least one cyanated perylene compound or mixtures thereof as fluorescent dye; to the use of these color converters and to lighting devices comprising at least one LED and at least one color converter.
