Thermally activated delayed fluorescence (TADF) materials for pure organic compounds have been considered as an attractive technology to obtain 100% internal quantum efficiency (IQE) without using rare metals. Very recently, light-metal-based TADF materials have been reported and achieved high-performance organic light-emitting diodes (OLEDs). In this study, we have developed a series of fluorinated aluminum complex-based carbazole dendrimer and evaluated optical properties and device performances.
