摘要

双核Pt（II）配合物新型蝴蝶状的双核Pt（II）配合物，具有非氟化NHC配体的Di-Pt-CH3和Di-Pt-CD3被开发。它们表现出蓝色发射和较短的发射寿命。PhOLED和PS-TADF OLED的EQEmax分别为18.3%和25.4%，效率和寿命均高于Ir配合物。氘取代甲基（-CD3），显着提高了器件寿命。更多细节可以在sooo - byung Ko， Taekyung Kim， Yun-Hi Kim和同事的文章2402230中找到。

Blue Thermally Activated Delayed Fluorescent OLEDs With EQE up to 25% via 3MMLCT-Induced and Short-Lived Phosphorescent Dinuclear Pt(II) Sensitizers (Advanced Optical Materials 5/2025)

Dinuclear Pt(II) Complexes

The novel butterfly-like dinuclear Pt(II) complexes, Di-Pt-CH₃ and Di-Pt-CD₃ with non-fluorinated NHC ligands are developed. They exhibit blue emission and a short emission lifetime. The EQE_max of 18.3% and 25.4% are obtained from PhOLED and PS-TADF OLED, respectively with higher efficiency and lifetime than those of Ir complex. The deuterium-substituted methyl group (-CD₃), a significantly improved device lifetime. More details can be found in article 2402230 by Soo-Byung Ko, Taekyung Kim, Yun-Hi Kim, and co-workers.
