The dynamic chemical diversity of the numerous elements, ions and molecules that constitute the basis of life provides wide challenges and opportunities for research. In an article, author is Chen, Cheng, once mentioned the application of 573-17-1, Name is 9-Bromophenanthrene. Now introduce a scientific discovery about this category, Formula: https://www.ambeed.com/products/573-17-1.html.
Three new 1,8-naphthyridine-based thermally activated delayed fluorescence (TADF) emitters, 2,7-di(9,9-dimethylacridin-10(9H)-yl)-1,8-naphthyridine (DMAC-ND), 2,7-di(10H-phenothiazin-10-yl)-1,8-naphthyridine (PTZ-ND) and 2,7-di(10H-phenoxazin-10-yl)-1,8-naphthyridine (PXZ-ND), were designed and synthesized. They possessed twisted structures and small Delta E-ST, which could make them show excellent TADF and AIDF properties. Consequently, multi-color organic light-emitting diodes (OLED) based on emitters DMAC-ND, PTZ-ND and PXZ-ND were fabricated, which could achieve a maximum external quantum efficiency (EQE) of 14.1, 13.4 and 13.0%, respectively. Moreover, all devices exhibited relatively low turn-on voltages and low efficiency roll-off ranging from 4.5% to 20% at the luminance of 1000 cd m(-2) probably owing to the microsecond-scale delayed photoluminescence (PL) and AIDF properties of the emitters. Notably, a DMAC-ND-based non-doped device reached the luminance of 20000 cd m(-2) easily at the voltage of 6.5 V, and exhibited very low efficiency roll-off of 4.5% at the luminance of 1000 cd m(-2) and 33.6% at the luminance of 10000 cd m(-2).
