Abstract (in Japanese) (See Japanese page) 
(in English) In this study, the photophysical properties of eight bisamino-anthracene derivatives were investigated to identify materials capable of efficient triplet–triplet upconversion (TTU). Organic light-emitting diodes (OLEDs) enabling low-voltage operation via TTU were fabricated using each derivative. Among the eight devices, one exhibited monochromatic green emission, with light emission initiated at an applied voltage below the energy gap of the emitter. Furthermore, in OLEDs driven by charge recombination within the emission layer, the results indicate superior TTU efficiency and hole-transport characteristics compared with conventional TTU materials. These findings demonstrate the potential of the proposed materials to achieve higher efficiency in low-voltage-driven OLEDs than those based on single TTU emitters.
