5,6-DIPHENYL-5,6-DIHYDRO-DIBENZC,E1,2AZAPHOSPHORIN AND 6-PHENYL-6H-DIBENZOC,E1,2THIAZIN-5,5-DIOXIDE DERIVATIVES AND SIMILAR COMPOUNDS AS ORGANIC ELECTROLUMINESCENT MATERIALS FOR OLEDS

摘要

The invention relates to 5,6-diphenyl-5,6-dihydro- dibenz[c,e][1,2 ]azaphosphorin and 6-phenyl-6H-dibenzo[c,e] [1,2]thiazin-5,5 dioxide derivatives and similar compounds of the formula (1) as organic electroluminescent materials for use in organic electroluminescent devices, such as, for example, in organic light-emitting diodes (OLEDs), wherein, for the symbols used: Z is the same or different in each occurrence PAr² or S(=0); E is the same or different in each occurrence O or S if the symbol Z, to which this E binds, represents PAr² and O if the symbol Z,, to which this E binds, represents S(=0); L is selected from the group comprising NAr², O, S, S(=O)₂, P(=O)Ar², -X=X- or -C(=O)-NAr²; the remaining symbols are defined in the claims. The invention relates to synthetic examples of compounds according to the invention, to the production of OLEDs which contain said exemplary compounds, and to the results of said electroluminescent devices.
