Paragraph 0072; 0073; 0074; 0075; 0076, (2017/12/09)
The invention discloses an organic light-emitting material and an OLED (organic light-emitting diode) prepared from the same, and relates to the technical field of organic photoelectric materials. The material exhibits good thermal stability by introducing an anthracene-like rigid structure, the OLED is prepared from the material through diffraction, and the material is particularly used as a main body material of the OLED. The OLED has the characteristics of low driving voltage, high brightness, excellent heat resistance, high efficiency and the like, and is better than existing common OLEDs.

A new family of phosphine ligands bearing a bulky carbazolyl scaffold is described. With the combination of ligand 2a and Pd(OAc)2, difficult tri-ortho-substituted biaryl couplings are accomplished smoothly. In particular, the catalyst loading as low as 0.02 mol% of Pd for non-activated 2,6-disubstituted aryl chloride coupling can be achieved.
