新型1-苯基吡唑铱配合物发光材料的合成与应用

Ir(Ⅲ) complexes of heavy metals such elements can have a strong spin-orbit coupling. The original prohibited the triplet state transitions into permitting, Then achieve strong phosphorescence launch, Components can be greatly improved luminous efficiency. The light-emitting nature of such metal ions complexes mainly in the main ligand, and ancillary ligands can only fine-tuning it. A series of heteroleptic cyclometalate Ir complexes with acylamide derivants as ancillary ligands: (ppz)2Ir(ayl)、(ppz)2Ir(nap-ph-ayl) and (ppz)2Ir(Cl-ayl)，And by elemental analysis, melting point determination, diffusion, NMR methods and so on of synhetic compounds for structrual characterization. All the complexes give rise to resemble absorptions at around 250nm, and their solution emissions are all fell into the green light region but differ in the max emission wavelength about 610nm, which prove all the complexes are red phosphorescence complexes.
