제목 Synthesis and Optical Properties of Organic Emitters including Electron donor and Acceptor in a Molecule for OLED
초록 New OLED materials were synthesized by through boronylation, bromination, Suzuki aryl-aryl coupling and Buchwald-Hartwig amination. Optical properties were investigated by using UV-visible spectra and photoluminescence (PL) spectra. Each compound has dipoles because it has electron donor and acceptor in a molecule and they showed the solvatochromism. Although there was no big change in the UV-visible spectra, the more the solvent polarity was increased in the PL spectra, the more PLmax was red-shifted. Also, it seemed that the more the conjugation length of a core group was increased, the more each compound tended to red-shift in the UV-visible and the PL spectra. While DPAT-Ph and DPAT-N emitted strong light in a solution state with the naked eye, DPAT-An emitted very weak light in a solution state, but strong light in a thin film state. As a result of taking an aggregation-induced emission (AIE) active test, it was identified that DPAT-An uniquely showed AIE.
