本报告涉及采用绿色和可持续路线,使用枇杷叶提取物开发异质钯铁纳米复合材料(Pd-Fe@LLR NC)。开发的 Pd-Fe@LLR 使用各种技术进行了表征,即。紫外、红外 FE-SEM、XRD 和 VSM。此外,Pd-Fe@LLR 被用作交叉偶联反应的催化剂,以提供三环含氮杂环支架。值得注意的是,开发的 Pd-Fe@LLR 催化剂对 C C 和 C N 偶联反应表现出令人印象深刻的活性。此外,催化剂被磁力回收并重复使用九个循环,催化活性略有下降。
An organic light-emitting device having high efficiency and long lifespan including: a first electrode; a second electrode facing the first electrode; and an organic layer between the first electrode and the second electrode and including an emission layer, wherein the organic layer includes a first compound represented by Formula 1 and a second compound represented by Formula 2:
When compounds represented by Formulae 1 and 2 are included in the emission layer, organic light-emitting devices may exhibit improved driving voltage, improved luminance, improved efficiency, and/or improved lifespans.
Pd-Fe@LLR was characterized using various techniques viz. UV, IR FE-SEM, XRD and VSM. Further Pd-Fe@LLR was utilized as catalyst for cross‐coupling reaction to afford tricyclic nitrogen containing heterocyclic scaffolds. Of note, the developed Pd-Fe@LLR catalyst demonstrated impressive activity towards CC and CN coupling reactions. In addition, the catalyst was magnetically recovered and reused for nine cycles
