[5]-helicene and dibenzofluorene materials for use in organic light emitting devices |
摘要 |
Organic materials based on [5] helicenes or dibenzofluorenes are shown to have excellent properties for use in electroluminescent devices, including high stability and efficiency and low excimer formation. The materials may advantageously be adapted to have hole transport or electron transport capabilities in addition to emissive properties.
