3-Methyl-6-(3,5-difluorophenyl)imidazo[2,1-b]thiazole (mdfpit) and 3-methyl-6-(3,4,5-trifluorophenyl)imidazo[2,1-b]thiazole (mtfpit) were easily prepared from thiourea, acetone, and 3,5-difluorobenzoyl bromide or 3,4,5-trifluorobenzoyl bromide. These were used as primary ligands to synthesize twelve phosphorescent IrIIIcomplexes with picolinic acid (pic), isoquinoline-3-carboxylic acid (3-IQA), quinoline-2-carboxylic acid (2-QA), 2-(pyridin-2-yl)phenol (2-ylppy), 2-(2,4-difluorophenyl)pyridine (dfppy), and pyridine-2-sulfonic acid (2-sappy) as auxiliary ligands. Their structures, photoluminescence, and electrochemical properties were investigated. Upon introducing more fluorine atoms into the benzene ring of the primary ligand, the thermal stability, photoluminescence quantum yield (PLQY), LUMO energy level, and luminous efficiency of the resulting IrIIIcomplexes are significantly improved, and the photoluminescence emission spectra are blue-shifted. Their maximum emission wavelengths are present in the range of 517-618 nm, and the luminous colors span from the green to red light region. Using the synthesized IrIIIcomplexes as emitters, LED chips based on InGaN chip excitation were developed, which showed good performances. Among all LEDs, the PLQY of the (mtfpmt)2Ir(pic) based LED is 58.4%, and the luminous efficiency is as high as 17.11 lm W?1; the luminous efficiency of the (mdfpmt)2Ir(2-QA) based LED is 3.41 lm W?1with CIE coordinates of 0.60 and 0.38, which are very similar to the saturated standard red light emission. The results demonstrate the potential of the studied IrIIIcomplexes as candidates for LED materials.

The invention discloses ten iridium (III) complexes, which are characterized in that: the main ligands of the complexes are 3-methyl-6-phenylimidazole[2, 1-b]thiazole (mpmt) and 3-methyl-6-(4-(trifluoromethyl)phenyl)imidazo[2, 1-b]thiazole (mtfpmt) respectively, and the auxiliary ligands are 2-picolinic acid (pic), isoquinoline-3-formic acid (3-IQA), quinoline-2-carboxylic acid (2-QA), 1-phenylisoquinoline (piq) and 2-(2, 4-difluorophenyl)pyridine (dfppy) respectively, and the structures are shown as the specification, wherein the definition of X substituent group is selected from one of twogroups of complexes. Light-emitting diodes prepared from the complexes have a maximum emission wavelength of 540.3-627.8nm and light-emitting efficiency of 0.18-3.01 lm.W, wherein (mtfpmt)2Ir(pic)emits pure green light, and (mpmt)2Ir(2-QA) emits pure red light, and the color purity is high. near white light can be obtained after mixing of the light emitted by (mtfpmt)2Ir(dfppy) and a galliumnitride chip, therefore the complexes can be used for making of white light LED. Excellent performance of the devices indicates that the complexes have application value in preparation of organic photoluminescent and electroluminescent devices. The invention discloses a structure and a synthesis method of the complexes, and a structure and a preparation method of organic photoluminescent devices.
