Synthesis and Characterization of Platinum(II) Complexes with Bis(3-(trifluoromethyl)-pyrazolyl)-borate Auxiliary Ligands
Five novel square-planar platinum(II) complexes with electron-deficient bis(3-(trifluoromethyl)-pyrazolyl)-borate auxiliary ligands were synthesized in yields ranging from 31% to 76%. The complexes feature cyclometalating C^C*-ligands based on phenyl imidazopyridines with different substituents (H, 3-Me, 4-Me, 4-EtO, and 4-CF3O). All five complexes emit light in the green-blue region with photoluminescence quantum yields between 32% and 56% (2 wt % in PMMA).
Five new square-planar platinum(II) complexes incorporating electron-deficient bis(3-(trifluoromethyl)-pyrazolyl)-borate auxiliary ligands were synthesized with yields ranging from 31 to 76%. These complexes contain cyclometalating C^C*-ligands derived from phenyl imidazopyridines, bearing various substituents (H, 3-Me, 4-Me, 4-EtO, and 4-CF3O). All five complexes exhibit green-blue emission with photoluminescence quantum yields between 32 and 56%.
期刊介绍：
Inorganic Chemistry publishes fundamental studies in all phases of inorganic chemistry. Coverage includes experimental and theoretical reports on quantitative studies of structure and thermodynamics, kinetics, mechanisms of inorganic reactions, bioinorganic chemistry, and relevant aspects of organometallic chemistry, solid-state phenomena, and chemical bonding theory. Emphasis is placed on the synthesis, structure, thermodynamics, reactivity, spectroscopy, and bonding properties of significant new and known compounds.
