Cyano-Isocyanide Iridium(III) Complexes with Pure Blue Phosphorescence

Louise M. Canada et al.

Summary: This paper presents a series of six neutral, blue-phosphorescent cyclometalated iridium complexes with efficient blue photoluminescence. These complexes are prepared by substituting cyanide ancillary ligands onto chloride precursors and show good phosphorescence efficiency when doped into poly(methyl methacrylate) films.

Synthesis and characterization of blue-violet emitting iridium(III) complex coordinated via chlorinated ancillary ligand

Supriya Debnath et al.

Summary: A new iridium(III) complex with blue-violet emission properties was successfully synthesized and characterized, exhibiting an emission band at 395 nm with a quantum yield of 0.06. Experimental and theoretical studies supported the fact that the nature of emission is an admixture of (IL)-I-3 and (MLCT)-M-3 state.

Bis-cyclometalated iridium(iii) complexes with terpyridine analogues: syntheses, structures, spectroscopy and computational studies

Haleema Y. Otaif et al.

Summary: Two ligands based on a 2,6-disubstituted pyridine bridge were synthesized to introduce bis-quinoxalinyl units in iridium(iii) luminescent complexes. The emission features of the complexes were found to be influenced by both metal-to-ligand charge transfer and intra-ligand charge transfer, with emission wavelength tunable by substituents on the quinoxaline ring.

Synthesis and luminescence properties of two cross-linkable Ir(III) complexes

Xiaoxiao Liu et al.

Summary: The two cross-linkable iridium(III) complexes showed good thermal stability and emitted green-yellow light with excellent quantum yields. The vacuum-processed electroluminescence device made from Ir(L)(2)(acac) demonstrated higher efficiency and brightness compared to the solution-processed device, which had slightly lower efficiency and brightness.

Synthesis and photoelectric properties of IrIII complexes using fluorobenzylimidazole[2,1-b]thiazole derivatives as primary ligands

Peng-bin Si et al.

Summary: The study focuses on the synthesis of phosphorescent Ir-III complexes using primary ligands mdfpit and mtfpit with various auxiliary ligands. Introducing more fluorine atoms into the benzene ring enhances the thermal stability, photoluminescence quantum yield, and luminous efficiency of the resulting complexes. LED chips based on these complexes show good performances, with (mdfpmt)2Ir(pic) exhibiting the highest PLQY and luminous efficiency.
