We demonstrate that two new cationic Ir(III) complexes exhibit an interesting piezochromism, and their emission color can be smartly switched by grinding and heating. This is the first example that the Ir(III) complexes display piezochromic phosphorescence.
Three new heteroleptic cationic iridium complexes of the form [Ir(C^N)(btl)](+), where btl = 1,1'-benzyl-4,4'-bi-1H-1,2,3-triazolyl and C^N = 2-phenylpyridine (ppyH) (1), 1-benzyl-4-phenyl-1H-1,2,3-triazole (phtl) (2) or 1-benzyl-4-(2,4-difluorophenyl)-1H-1,2,3-triazole (dFphtl) (3), were synthesized and isolated as their hexafluorophosphate (PF6(-)) salts and fully characterized. The single cr...
The attachment of molecular catalysts to conductive supports for the preparation solid-state anodes is important development devices electrocatalytic water oxidation. and characterization three cyclopentadienyl iridium(III) complexes, Cp*Ir(1-pyrenyl(2-pyridyl)ethanolate-κO,κN)Cl (1) (Cp* = pentamethylcyclopentadienyl), Cp*Ir(diphenyl(2-pyridyl)methanolate-κO,κN)Cl (2), [Cp*Ir(4-(1-pyrenyl)-2,2...
The structural and energetic characterization of metal complexes is important in catalysis and photochemical applications. Unraveling their modes-of-action can be greatly assisted by computation, which typically is restricted to computationally demanding methods including electronic structure calculations with density functional theory. Here, we present an empirical force field based on valence...
Atropo-enantioselective biaryl coupling through C−H bond functionalization is an emerging technology allowing direct construction of axially chiral molecules. This approach largely limited to electrophilic partners. We report a highly atropo-enantioselective arylation tetralone derivatives paired with aryl boronic esters as nucleophilic components. The transformation catalyzed by cyclopentadien...
The straightforward synthesis and photophysical properties of a new series of heteroleptic iridium(III) bis(2-arylimidazole) picolinate complexes are reported. Each complex has been characterized by nuclear magnetic resonance, UV-vis, cyclic voltammetry, and photoluminescent angle dependency, and the emissive properties of each are described. The preferred orientation of transition dipoles in e...
