Abstract

The present invention relates to a cyanoaryl substituted compound of formula (I), (I) wherein m is 0-4; R2, R3, R4 and R5 are selected from hydrogen, chlorine, bromine and C6-C24-aryl, which carries one to three cyano; each R1 independently from each other is selected from bromine, chlorine, cyano, —NRaRb, C1-C24-alkyl, C1-C24-haloalkyl, C1-C24-alkoxy, C1-C24-haloalkoxy, C3-C24-cycloalkyl, heterocycloalkyl, heteroaryl, C6-C24-aryl, C6-C24-aryloxy, C6-C24-aryl-C1-C10-alkylene, etc., with the proviso that at least one of the radicals R1, R2, R3, R4 and R5 is C6-C24-aryl, which carries one to three cyano; X is O, S, SO or SO2; A is a diradical of the formulae (A.1), (A.2), (A.3), or (A.4) wherein *, R6, (R7)n, (R8)o and (R9)p are as defined in the claims and in the description. The invention also relates to the use of said compound(s) in color converters, to said color converters and their use, to lighting devices, to a backlight unit for liquid crystal displays; a liquid crystal display device and a self-emissive display device comprising at least one compound (I).
