- Iridium complex and organic light emitting device thereof
-
The invention discloses an iridium complex and an organic light emitting device thereof and relates to the technical field of organic photoelectric materials. The iridium complex is of a structure asshown in the formula (I). Due to an electron-rich double-nitrogen coordination structure in the iridium complex structure, trivalent metal cation in the center can be beneficially stabilized, and meanwhile, electron cloud distribution on the metal iridium can be affected, so that photoelectric properties of whole complex molecules can be greatly influenced; and in addition, a four-membered ring formed by ligand of the double-nitrogen coordination structure and the metal has rigidity, unexpected vibration energy loss can be favorably reduced, and high-efficiency light emission properties can beachieved. By adjusting substitution groups, the complex is good in thermal stability and chemical property. The iridium metal organic complex can be prepared into a device and can be particularly used as a doping material, and the device has the advantages of being low in driving voltage and high in light emission efficiency and is prior to conventional common OLEDs (Organic Light Emitting Devices).

- Improved synthesis of azaheteroarylboronic acids using tris-trimethylsilylborate under mild conditions
-
A new family of azaheteroarylboronic acids was synthesized with good yields (70% to 75%). The proposed strategy utilizes an improved transmetalation reaction from Grignard azine reagents and tris-trimethylsilylborate, little used until now.
