BROMINE-SUBSTITUTED RYLENE TETRACARBOXYLIC ACID DERIVATIVES, AND THE USE THEREOF

摘要

The present invention relates to bromine-substituted rylene tetracarboxylic acid derivatives of the general formula (I), wherein n is 2, 3, or 4; Rn1, Rn2, Rn3, and Rn4 are halogen or cyano, specifically for Br, wherein at least one of the radicals Rn1, Rn2, Rn3 or Rn4 is Br; Y1 and Y2 are O or NRb; wherein Rb is hydrogen or an organyl radical; Z1, Z2, Z3 and Z4 are O, wherein in case that Y1 is NRa, one of the radicals Z1 and Z2 may also be NRC, wherein the radicals Ra and Rc together are a bridging group having 2 to 5 atoms between the flanking bonds, and wherein in case Y2 is NRb, one of the radicals Z3 and Z4 may also be NRd, wherein the radicals Rb und Rd together are a bridging group having 2 to 5 atoms between the flanking bonds; to the production of compounds of the general formula I by means of reaction of a corresponding compound, wherein at least one of the radicals Rn1, Rn2, Rn3 and/or Rn4 is hydrogen, having N,N'-dibromisocyanuric acid, and to the use of compounds of the general formula I as emitter materials, charge transport materials, or exciton transport materials.
