Abstract
The present invention provides organoselenium compounds comprising dibenzoselenophene, benzo[b]selenophene or benzo[c]selenophene and their uses in organic light emitting devices.
Claims2
An organoselenium compound selected from the group consisting of
- wherein each of R1, R2, R3, R4, R5, R6 and R7 indicates an optional substituent to any possible position in the relevant moiety and each line linking two molecular moieties indicates attachment between the two moieties at any possible positions on the respective moieties.
An organic light emitting device, comprising an organic layer positioned between an anode layer and a cathode layer, said organic layer comprising an organoselenium material, wherein said organoselenium material is a compound comprising a benzo[c]selenophene selected from the group consisting of
- wherein each of R1, R2, R3, R4, R5, R6, and R7 is an optional substituent to any possible position in the relevant moiety, and each line linking two moieties indicates attachment between the two moieties at any possible positions on the respective moieties.
