A novel tridentate ligand N-(6-(diphenylphosphoryl)pyridin-2-yl)-2,2,2-trifluoroacetamide (DPPOPFA) was designed and synthesized. Crystal structure of the ligand revealed the “keto” form of ligand in solid state other than the “enol” one, and it was also found that two kinds of molecules with different conformations were connected by hydrogen bonding between amide N–H and phosphoryl P=O. This ionic...
The research on electroluminescence based on europium(III) complexes has come to an important phase. This article reviewed the progresses in photoluminescence and electroluminescence of Eu(III) complexes in recent years from the views of the design of Eu(III) complexes and optimization of device structures, and discussed some important factors influencing electroluminescence performance. The problems...
