Abstract

The present invention relates to cyanated compounds of the formula (I) wherein at least one of the radicals R², R³, R⁴ and R⁵ is CN, and the remaining radicals are selected from hydrogen, chlorine and bromine; X is O, S, SO or SO₂; m is 0, 1, 2, 3 or 4; R¹ is selected from bromine, chlorine, cyano, —NR^aR^b, 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.; A is a diradical selected from diradicals of the general formulae (A.1), (A.2), (A.3), and (A.4) wherein R⁶, (R⁷)_n, (R⁸)_o and (R⁹)_p are as defined in the claims and in the description. The invention further relates to color converters comprising at least one polymer as a matrix material and at least one cyanated compound of formula (I) or mixtures thereof as a fluorescent dye, to the use of the color converters and to lighting devices comprising at least one LED and at least one color converter.

Claims
