Abstract:
Color converter comprising at least one polymer and at least one organic fluorescent dye comprising at least one structural unit of the formula (I) where the structural unit may be mono- or polysubstituted by identical or different substituents and where one or more CH groups of the six-membered ring of the benzimidazole structure shown may be replaced by nitrogen.
Abstract:
Disclosed is an organic solar cell with a photoactive region which comprises at least one organic donor material in contact with at least one organic acceptor material, wherein the donor material and the acceptor material form a donor-acceptor heterojunction and wherein the photoactive region comprises at least one substituted perylene.
Abstract:
The invention relates to a method for producing the quaterrylene-3,4:13,14-tetracarboxy diimides of general formula (I), wherein R, R' independently represent hydrogen or optionally substituted C1-C30 alkyl, C3-C8 cycloalkyl or aryl or hetaryl. The inventive method is characterized by reacting the perylene-3,4-dicarboximide of the general formula (IIa) in the presence of a base resistant, high-boiling, organic solvent and an alkali-containing or alkaline earth-containing base with the perylene-3,4-dicarboximide of the general formula (IIb), wherein X represents hydrogen, bromine or chlorine.
Abstract:
The invention relates to heptarylene and octarylene tetracarboxylic acid diimides of general formula (I), precursors thereof or mixtures thereof, methods for the production thereof, and the use thereof.
Abstract:
The present invention relates to fluorinated rylenetetracarboxylic acid derivatives, to a process for their preparation and to their use, especially as n-type semiconductors.
Abstract:
