Research on sp3 C-H Bond Halogenation and Synthesis of Organic Compounds for OLEDs.
- Abstract
- In chapter 1.
For the compound having an ester group in a benzylic position, bromination using a bromination reagent was tested to obtain optimal reaction conditions, and a maximum yield of 87.4% was obtained. The reactions were expanded for various types of ester groups and acetate substrates, and brominated products were obtained at the alpha position of the ester groups.
In chapter 2.
OLED molecules were designed and synthesized using carbazole derivatives widely known as highly efficient electron donors and triazine derivatives used as electron acceptors. Also, when ir(ppy)2acac and ir(mphmq)2tmd were used as dopants in the device, green emission and red emission were observed respectively, and their maximum QE values were 22.2% and 25.4%.
