- Aromatic amine derivative and organic light-emitting device thereof
-
The invention provides an aromatic amine derivative and an organic light-emitting device thereof, and relates to the technical field of organic photoelectric materials. The preparation method of the compound is simple, raw materials are easy to obtain, the high hole mobility and Tg and the good stability and film-forming property are achieved, the derivative has the proper highest occupied molecular orbital, and can be adopted as a first hole transmission layer and can also be adopted as a second hole transmission layer. When the derivative is adopted as the first hole transmission layer, theenergy level difference between a light-emitting layer and an anode interface can be lowered; when the derivative is adopted as the second hole transmission layer, the energy level difference betweenthe light-emitting layer and the first hole transmission layer can be lowered, and meanwhile point sum balance inside the light-emitting layer can be achieved. The derivative is applied to an OLED, the light-emitting efficiency and the color purity of the device can be remarkably improved, the service life of the device can be prolonged, the driving voltage of the device can be lowered, and the OLED material is good in performance.

- Quantitative formation of [2]catenanes using copper(I) and palladium(II) as templating and assembling centers: The entwining route and the threading approach
-
Transition metal-mediated templating and self-assembly have shown powerful potentials for the synthesis of interlocked molecules. These two strategies were combined in designing and preparing a new type of coordination catenanes incorporating Cu(I) and Pd(II) metal centers. The ligand designed here contains a phenanthroline core and pyridine sidearms (compound 1). Using this phenanthroline-pyridine conjugated ligand, two approaches were examined, which were shown to be surprisingly efficient for the catenane synthesis: the entwining route (entwining of two ligands around Cu(I) followed by Pd(II) clipping) and the threading approach (Cu(I)-templated threading of a cyclic ligand on an acyclic ligand followed by the PD(II) clipping of the second ring). In the former method, stepwise treatment of 1 with Cu(CH3CN)4PF6 (templating center) and enPd(NO3)2 (assembling center) gives rise to the quantitative formation of CuPd2 catenane 18. In the latter method, Cu(I) templates the threading of phenanthroline-containing macrocycle 2 on ligand 1, which is followed by Pd(II) clipping to give hetero catenane 20. In both approaches, the formation of catenanes is convincing thanks to the strong templating effect of Cu(I), while the ring closure steps are efficiently furnished by Pd(II)-directed self-assembly.

Exclusion of competitive ligands is found to be the central requirement for obtaining solutions of constitutionally homogeneous, high-molecular-mass coordination polymers from kinetically unstable pseudo-tetrahedral complexes of copper(I) and o-phenanthroline derivatives.
