摘要:
The present invention describes novel organometallic compounds that are phosphorescence emitters. Such compounds can be used as active components (=functional materials) in a range of different applications that can be assigned in the broadest sense to the electronics industry. The compounds according to the invention are described by the formulae (I), (Ia), (II) and (IIa).
摘要:
The invention relates to a method for the production of tertiary amines by reaction of secondary amines with aromatics or heteroaromatics in the presence of a base, a nickel or palladium compound and one or several phosphines, dialkoxy-, and/or diaryloxyphosphines in an inert solvent. Aromatic or heteroaromatics of this type play an important role in industry as reagents or intermediates for pharmaceuticals and agrochemicals and in diverse fine and electronics chemicals, above all in the rapidly growing field of organic semi-conductors, in particular in organic or polymeric light diodes, organic solar cells and organic ICs.
摘要:
The present invention relates to novel conjugated polymers comprising spirobifluorene units and their use in optoelectronic devices, preferably in, for example, displays based on polymeric organic light-emitting diodes.
摘要:
A process for preparing polymerizable biaryl derivatives comprises reacting an aromatic comprising a 6-membered ring which bears ester or benzylic OH groups in the 1,4 position with a second aromatic in a palladium-catalyzed cross-coupling reaction to give a biaryl and converting the ester or benzylic OH groups into polymerizable groups in one or more steps. The biaryls obtained are suitable for preparing polymers which are used as electroluminescence materials.
