Asymmetric tris-Heteroleptic IridiumIII Complexes Containing a 9-Phenyl-9-phosphafluorene Oxide Moiety with Enhanced Charge Carrier Injection/Transporting Properties for Highly Efficient Solution-Processed Organic Light-Emitting Diodes

A cyclometalating ligand containing a 9-phenyl-9-phosphafluorene oxide (PhFlPO) moiety has been synthesized and used to construct asymmetric tris-heteroleptic cyclometalating IrIII complexes in combination with other ppy-type (Hppy = 2-phenylpyridine) ligands containing a functional group with a different charge carrier injection/transporting character. Their photophysical properties, electrochemical behaviors, and electroluminescent (EL) performances have been characterized in detail. Time-dependent density functional theory (TD-DFT) and natural transition orbital (NTO) calculation were carried out to gain insight into the photophysical properties of these complexes. The NTO results show that the characters of the lowest triplet excited states (T1) can be delicately manipulated through the combination of different cyclometalating ligands. In addition, the strong electron injection/transporting (EI/ET) ability associated with the PhFlPO moiety can confer EI/ET properties to the asymmetric tris-heteroleptic cyclometalating IrIII complexes. Consequently, the solution-processed organic light-emitting diodes/devices (OLEDs) based on these asymmetric tris-heteroleptic IrIII phosphorescent complexes can exhibit outstanding electroluminescent (EL) performances with the maximum external quantum efficiency (ηext) of 19.3%, current efficiency (ηL) of 82.5 cd A-1, and power efficiency (ηP) of 57.3 lm W-1 for the yellow-emitting device. These results show the great potential of a PhFlPO moiety in developing phosphorescent emitters and functional materials with excellent EI/ET properties.

Asymmetrical iridium (III) phosphorescent complex containing dibenzo-phosphorus mixed with cyclopentadienyl group, and synthesis method of asymmetrical iridium (III) phosphorescent complex

The invention relates to an asymmetrical iridium (III) phosphorescent complex containing a dibenzo-phosphorus mixed with cyclopentadienyl group, and a synthesis method of the asymmetrical iridium (III) phosphorescent complex. The synthesis method comprises the steps of synthesizing a ligand L-PO by taking 2-phenylpyridine and p-bromophenyl boronic acid as raw materials, and carrying out a Suzuki coupling reaction to synthesize 2-(4-bromophenyl) pyridine; enabling the 2-(4-bromophenyl) pyridine to have a reaction with n-butyl lithium and trimethyl borate to generate 4-(2-pyridyl) phenyl boronic acid; enabling the 4-(2-pyridyl) phenyl boronic acid to have a reaction with o-dibromobenzene for carrying out Suzuki coupling to generate a pyridine derivative having a 2-bromobiphenyl structure; enabling a Grignard reagent of the compound to have a reaction with dichlorophenyl phosphine, and carrying out a ring closing reaction under a catalytic condition of palladium acetate to obtain the ligand L-PO containing the dibenzo-phosphorus mixed with cyclopentadienyl group. The asymmetrical iridium (III) phosphorescent complex containing the dibenzo-phosphorus mixed with cyclopentadienyl group has excellent electron injection/transmission performance, and can remarkably improve the electroluminescence efficiency of an organic electroluminescence device based on the materials.
