| abstract |
The present invention relates to 5,6-diphenyl-5,6-dihydrodibenz[c,e][1,2]azaphosphorin and 6-phenyl-6H-dibenzo[c,e][1,2]thiazine 5,5-dioxide derivatives and similar compounds of the formula (1) as organic electroluminescent materials for use in organic electroluminescent devices, for example in organic light-emitting diodes (OLEDs), where the symbols used are as follows: Z is the same or different at each instance and is PAr 2 or S(═O); E is the same or different at each instance and is O or S when the symbol Z to which this E binds is PAr 2 , and O when the symbol Z to which this E binds is S(═O); L is selected from the group consisting of a single bond, NAr 2 , O, S, S(═O) 2 , P(═O)Ar 2 , —X═X— and —C(═O)—NAr 2 ; the rest of the symbols are defined in the claims. The present invention discloses synthesis examples of inventive compounds, productions of OLEDs containing these example compounds, and results for these electroluminescent devices. |
