| description | The invention provides a yellow phosphorescent pyrimidine iridium complex and a preparation method thereof and belongs to the technical field of electrophosphorescent materials. The preparation method comprises the following steps: preparing cyclometalated ligand, preparing a chlorine bridging iridium complex, and preparing an iridium complex, and thus obtaining the yellow phosphorescent pyrimidine iridium complex with the structural formula being (img file= 'DSA0000111161700000011. TIF' wi= '632' he= '447'). A CH2Cl2 solution of the iridium complex can emit yellow phosphorescence under exciting light of 400nm, and the largest emission peak is 558nm. An organic electroluminescence device made of the iridium complex as a guest material is good in luminescence property. The preparation method is simple in preparation process, and raw materials are easy to obtain. |
