Abstract:
An electroluminescent arrangement which comprisesa substrate, an anode, an electroluminescent element and a cathode, and said anode or said cathode is transparent in the visible spectral range and the electroluminescent element is a single layer consisting essentially of an optionally substituted tris-1,3,5-(aminophenyl)benzene compound A) or mixtures thereof, with optionally one or more hole-transporting compounds which have a structure different from formula (I), whereinR2 represents hydrogen, optionally substituted alkyl or halogen, R3 and R4, independently of one another, represent optionally substituted C1-C10-alkyl, alkoxycarbonyl-substituted C1-C10-alkyl, optionally substituted aryl, optionally substituted aralkyl or optionally substituted cycloalkyl, a luminescent component B) which is a compound corresponding to formula (II): and whereinMe represents a metal, m is a number from 1 to 3, n is 1,2 or 3 and z independently in both forms represents atoms which complete a nucleus which contains at least 2 condensed rings; or mixtures thereof; and optionally a transparent polymeric binder C).
