Phosphorescent Ir(iii) complexes bearing double benzyldiphenylphosphine cyclometalates; strategic synthesis, fundamental and integration for white OLED fabrication

Fluorinated Triazoles and Tetrazoles

“…The photo-and electroluminescence properties of a series of novel, heteroleptic, mer -cyclometallated iridium complexes have been fi ne-tuned from green to blue by changing the substituents on the 3-trifl uoromethyl-1,2,4-triazolylpyridyl ring of the ligand [ 176 , 177 ]. Chi, Chou, Wu et al synthesized Ir(III) emissive complexes with 5-pyridyl-3-trifl uoromethyl-1,2,4-triazole ligand which might be used in white OLEDs technologies [ 178 ].…”

Phosphine‐Directed CH Borylation Reactions: Facile and Selective Access to Ambiphilic Phosphine Boronate Esters

“…Notably, there are numerous examples of phosphine-directed CÀH activation of analogous substrates by iridium complexes in the literature to support the feasibility of these intermediates. [32][33][34][35] The proposed catalytically active complex is a bisboryl iridium(III) complex (F), rather than the generally accepted trisboryl complex due to the bidentate ligand serving as an LX-type ligand. [36] Since one of the boryl substituents is replaced by a carbon-based X ligand, the coordination of a second phosphine does not lead to a coordinatively saturated iridium complex.…”

Pure white OLED based on an organic small molecule: 2,6-Di(1H-benzo[d]imidazol-2-yl)pyridine

“…White OLEDs have potential applications for backlighting display and general illumination because of their cost-effective fabrication [1-4], high light-emitting efficiency [5-8] and low-energy consumption [9][10][11][12]. Therefore, over the past decades, extensive studies have been performed on the development of white OLED [13][14][15][16]. It is not easy to fabricate a pure white OLED because of required appropriate multiemission and emissive intensity, so, there is much work for the preparations of pure white OLEDs.…”
