제목 Synthesis of thermally activated delayed fluorescene materials for organic light emitting devices
초록 Although phosphorescent materials containing heavy-metal center showed higher efficiency compared to those of fluorescence materials, these phosphorescent materials have difficulties in practical applications for blue emission. Recently, Adachi group reported high external quantum efficiencies over 20% with thermally activated delayed fluorescence (TADF) materials. In this work, we also synthesized two new TADF materials (TADF-1 and TADF-2) with donor-acceptor structures. While the solid photoluminescence emission of both compounds was observed at around 405 nm, phosphorescent emission of TADF-1 and TADF-2 measured in a 2-methyl-tetrahydrofuran at 77 K appeared at 440 nm and 520 nm, respectively. We will investigate the effect of molecular structure of the synthesized new TADF materials on their physical properties.
