摘要

High photoluminescence quantum efficiency (PLQY) and simple molecular structure in a full-color emitting material system are two crucial issues for cost-effective multicolor display applications. Herein, a new tailor-made fluorescent core (pyrido[2,3-b]pyrazine) is designed and synthesized. Through systematically fine-tuning the band gap, the versatile pyrido[2,3-b]pyrazine family exhibits a wide range of emissions spanning the entire visible region from blue to red. By reasonable choice of donor units, two thermally activated delayed fluorescence (TADF) molecules are obtained and the resulting OLEDs exhibit a yellow emission and an orange emission with high EQEs of up to 20.0% and 15.4%, respectively.
