Abstract Tri-coordinate organoboron compounds have received great attention in the fields of optoelectronic applications, such as anion sensors and OLEDs, due to their high Lewis acidity and intriguing photophysical properties. During recent years, our group has developed novel triarylboron-based anion sensors that can feature enhanced binding affinity or turn-on luminescence response. As well, triarylboron compounds were also utilized as electron-acceptors or emitters for high-efficiency OLEDs. On the other hands, the boron cluster compound, such as o-carborane, has attracted as a new class of steric and electronic auxiliary in the luminescent materials. Our group first reported that the o-carborane containing cyclometalated Ir(III) complexes can be used as highly efficient, color-tunable phosphorescent emitters in OLEDs. It was revealed that o-carborane can affect both the inductive and conjugative electronic effects. In particular, the quantum efficiency of Ir(III) complexes was shown to be strongly affected by the carborane groups. In this presentation, recent development and photonic applications of organoboron and boron cluster compounds will be discussed.
