Substituent effect on photo- and electroluminescence properties of heteroleptic cyclometalated platinum(II) complexes based on a 2-(dibenzo[b,d]furan-4-yl)pyridine ligand

Functional Materials Based on Cyclometalated Platinum(II) β-Diketonate Complexes: A Review of Structure–Property Relationships and Applications

“…cyclometalating ligands supported by diketonate derivatives have been assessed recently. A minor change in the functional group or position has a remarkable effect on their PL properties [ 44 ]. It has been demonstrated that the topology/connectivity of metal to ligand influences the photophysical properties, and this has been exploited to realize long-lived 3 IL or dual (fluorescence and phosphorescence) emission [ 45 , 46 ] and charge transfer (CT) [ 47 ].…”

(2-[4-Methylpyrazol-1-yl]phenyl)platinum(II) (1,3-bis[1-methyl-1H-pyrazol-4-yl]propane-1,3-dione)

“…The photophysical and photochemical properties of Pt(II) complexes are strongly dependent on the type of the coordinating ligands [5]. Pt(II) complexes bearing monodentate ligands are known to exhibit poor luminescence.…”

Transition-metal-free synthesis of functional 2-arylphenols by an intermolecular SNAr reaction between dibenzofurans and various nucleophiles

“…Dibenzofuran is an important class of organic frameworks, and could be obtained by numerous methods in one to two steps. 11 In this regard, the selective C–O bond cleavage and subsequent transformation of dibenzofurans are highly desirable and constitute appealing strategies to yield functionalized 2-arylphenols (Scheme 2b). The groups of Yorimitsu and Chatani disclosed the C–O activation of dibenzofurans and coupling with a Grignard reagent and trimethylaluminum in the presence of a nickel catalyst.…”
