Abstract

Abstract Translated from German Verfahren zur Konzentrierung von Licht mit Hilfe von fluoreszierenden Verbindungen der Formel <IMAGE> in der R¹ unabhängig voneinander keine wasserlöslich machende Gruppen enthaltende ortho-substituierte aromatische oder heterocyclische Reste sind, sowie neue Perylen-3,4,9,10- tetracarbonsäurediimide der Formel I in der R¹ <IMAGE> in der A¹ und A² Waserstoff oder einer der Reste A¹ oder A² Isopropyl und der andere Wasserstoff bedeuten. Die Verbindungen I sind sehr lichtecht und wandeln eingestrahltes Licht in hoher Ausbeute in Fluoreszenzlicht um. Process for concentrating light with the aid of fluorescent compounds of the formula <IMAGE> in which R¹ are independently of one another no ortho-substituted aromatic or heterocyclic radicals containing water-solubilizing groups, and new perylene-3,4,9,10-tetracarboxylic acid diimides of the formula I in R¹ <IMAGE> in A¹ and A² is hydrogen or one of A¹ or A² isopropyl and the other is hydrogen. The compounds I are very lightfast and convert incident light into fluorescent light in high yield.
