Design and Synthesis of Heteroleptic Cyclometalated Iridium(III) Complexes Containing Quinoline-Type Ligands that Exhibit Dual Phosphorescence.
The design and synthesis of some cyclometalated iridium(III) complexes containing quinoline-type ligands as ancillary ligands are reported. The emission spectra of Ir(III) complexes containing a quinolinolate (6, 8, 10) moiety exhibit a single emission peak at ca. 590 nm, resulting in a red colored emission. However, Ir(III) complexes containing 8-sulfonamidoquinoline ligands (11, 13-21) exhibi...
متن کاملCationic heteroleptic cyclometalated iridium(III) complexes containing phenyl-triazole and triazole-pyridine clicked ligands.
Novel heteroleptic iridium complexes containing the 1-substituted-4-phenyl-1H-1,2,3-triazole (phtl) cyclometalating ligand have been synthesized. The 3+2 Huisgen dipolar cycloaddition method ('click' chemistry) was utilized to prepare a class of bidentate ligands (phtl) bearing different substituents on the triazole moiety. By using various ligands (phtl-R1 and pytl-R2) (R1 = adamantane, methyl...

Novel heteroleptic iridium complexes containing the 1-substituted-4-phenyl-1H1,2,3-triazole (phtl) cyclometalating ligand have been synthesized. The 3+2 Huisgen dipolar cycloaddition method (‘click’ chemistry) was utilized to prepare a class of bidentate ligands (phtl) bearing different substituents on the triazole moiety. By using various ligands (phtl-R1 and pytl-R2) (R1=adamantane, methyl an...
متن کاملThe synthesis and photophysics of tris-heteroleptic cyclometalated iridium complexes.
Herein we report the synthesis and photophysical study of tris-heteroleptic complexes of the general formula IrLL'(acac), where L and L' are two differently substituted 2-phenylpyridines (ppyH) and acacH is 2,4-pentanedione, using a combinatorial approach that could be employed for many ligand combinations. The tris-heteroleptic complexes and the analogous bis-heteroleptic complexes of the form...
متن کاملHighly emissive platinum(II) complexes bearing carbene and cyclometalated ligands.
A series of heteroleptic platinum(II) complexes (1a-3a and 1b-3b) bearing a dicarbene ligand and a cyclometalated bidentate ligand have been prepared. Two of the complexes (1a and 3a) were characterized by X-ray diffraction analyses, confirming the square-planar structures. Detailed spectroscopic properties of the complexes have been studied, and two complexes, 3a and 3b bearing a carbene chela...
