Di-substituted pyrenes for luminescent applications
View Patent ↗This invention relates to electroluminescent 4,9-di-substituted pyrenes that are useful in electroluminescent applications. It also relates to electronic devices in which the active layer includes such a pyrene composition.
1. An organic electronic device comprising:
a. a first electrical contact layer;
b. a photoactive layer comprising a compound of Formula I:
wherein each one of R 1 through R 12 is independently selected from the group consisting of hydrogen, fluoro alkyl, fluoroalkyl, aryl, heteroaryl, diarylamino, dialkylamino, aryl(alkyl)amino, arylthio, alkylthio, arylseleno, alkylseleno, aryloxy, alkoxy, dialkylphosphino, diarylphosphino, dialkylphosphoryl, diarylphosphoryl, and thiophosphoryl; with the proviso that at least one of R 1 , R 3 , R 4 , R 6 , R 7 , R 9 , R 10 , and R 12 is selected from the group consisting of a fluoro group and a fluoroalkyl group; and
c. a second electrical contact layer;
wherein the compound of Formula I is an emissive dopant with blue emission.
