Substituted pyrenes and associated production methods for luminescent applications
View Patent ↗A substituted pyrene for electroluminescent applications and a method to produce the substituted pyrenes.
1. An organic electronic device comprising:
a first electrical contact layer;
a second electrical contact layer; and
an organic layer comprising a pyrene composition having Formula I
wherein R 1 and R 2 are independently selected from the group consisting of
2-naphthyl; 4-biphenyl, 3-biphenyl and 4-(1-naphthyl)-phenyl.
2. A device of claim 1 wherein the organic layer is an active layer.
3. A device of claim 2 wherein said active layer is a photoactive layer.
4. A device of claim 2 wherein said active layer is an electron transport layer.
5. A device of claim 2 wherein the pyrene composition comprises less than 20% by weight of the total weight of the active layer.
6. A device of claim 3 wherein the pyrene composition comprises less than 20% by weight of the total weight of the photoactive layer.
7. A device of claim 4 wherein the pyrene composition comprises less than 20% by weight of the total weight of the electron transport layer.
