Triphenylsilane-fluorene hybrids as host materials for green and blue phosphorescent organic light emitting diodes

Three triphenylsilane-fluorene hybrids as host materials have been synthesized and characterized for phosphorescent organic light emitting diodes (OLEDs). Triphenylsilane and fluorene moieties are introduced to increase thermal stability and triplet energy. Two kinds of devices - green and blue phosphorescent OLEDs - were fabricated to investigate electroluminescent properties of triphenylsilane-fluorene hybrids as host materials. Devices using these materials as phosphorescent hosts showed efficient green as well as blue electroluminescence with the maximum external quantum efficiencies of 9.01 and 10.7%, respectively.

Novel violet emitting material synthesized by stepwise chemical reactions

In this paper, we report the design and synthesis of a novel bipolar violet emitting molecule CzPySiSF. The carbazole and pyridine moieties are employed to facilitate charge injection and balance carrier transport, whereas the spirofluorene is used as the violet emitter. The three functional groups, i.e., carbazole, pyridine and spirofluorene, are connected to tetraphenylsilane in a stepwise fashion using classical coupling reactions such as Suzuki and Ullmann. The resultant bipolar molecule CzPySiSF exhibits very stable thermal properties and a uniform amorphous morphology. The introduction of spirofluorene greatly enhances the fluorescence quantum efficiency of the molecule; moreover the PL spectrum of CzPySiSF in THF is mainly located in the violet region. The EL spectrum of CzPySiSF matches well with the PL spectrum with a maximum at 408 nm. The violet OLED of CzPySiSF exhibits the maximum external quantum efficiency of 0.59%.
