Versatile boron-based thermally activated delayed fluorescence materials for organic light-emitting diodes

Abstract

During the last few years, organoboron-based thermally activated delayed fluorescence (TADF) materials have received extensive attention in optoelectronic area, owing to the unique electronegativity of boron atom. Herein, many research progress of organoboron-based TADF materials for organic optoelectronic devices is summarized. This review comprehensively documents the organoboron-based TADF materials according to the emission colors from blue to red-near-infrared (red-NIR), covering the molecular design strategies, photophysical properties, and optoelectronic performance in organic light-emitting diodes (OLEDs). The current progress and future challenges in this fast-growing fields are reviewed systematically, providing instructive guidance for the future research on high-performance TADF-OLEDs.
