Precisely regulating the double-boron-based multi-resonance framework towards pure-red emitters: high-performance OLEDs with CIE coordinates fully satisfying the BT. 2020 standard

Pure-red multi-resonance emitters are designed through precisely regulating the double-boron-based multi-resonance framework. The resulting OLEDs exhibit high efficiency and ideal CIE coordinates that fully satisfy the BT. 2020 standard.
