In Pursuit of Panchromatic Absorption in Metal Coordination Complexes: Experimental Delineation of the HOMO Inversion Model Using Pseudo-Octahedral Complexes of Diarylamido Ligands
(American Chemical Society, 2020-11-23)
The ability of a compound to broadly absorb light across the incident solar spectrum is an important design target in the development of molecular photosensitizers. The ‘HOMO inversion’ model predicts that for [(tpy)2Fe]2+ ...
Zn-Templated synthesis of substituted (2,6-diimine)pyridine proligands and evaluation of their iron complexes as anolytes for flow battery applications
(Royal Society of Chemistry, 2020-04-13)
Pseudo-octahedral iron complexes supported by tridentate N^N^N-binding, redox ‘non-innocent’ diiminepyridine (DIP) ligands exhibit multiple reversible ligand-based reductions that suggest the potential application of these ...
Diiminepyridine-Supported Phosphorus(I) and Phosphorus(III) Complexes: Synthesis, Characterization, and Electrochemistry
(Wiley VCH, 2020-06-08)
The synthesis of phosphorus coordination complexes of redox non-innocent diiminepyridine (DIP) ligands with the pnictogen in both the P(I) and P(III) oxidation states is presented. Electrochemical characterization indicates ...
Deep-Red Luminescence from Platinum(II) Complexes of N^N–^N-Amido Ligands with Benzannulated N-Heterocyclic Donor Arms
(American Chemical Society, 2020-08-18)
A synthetic methodology for accessing narrow-band, deep-red phosphorescence from mononuclear Pt(II) complexes is presented. These charge-neutral complexes have the general structure (N^N–^N)PtCl, in which the Pt(II) centers ...
Synthesis, Characterization and Coordination Chemistry of a Phenanthridine-Containing N-Heterocyclic Carbene Ligand
(Canadian Science Publishing, 2020-11-12)
An N-heterocyclic carbene ligand precursor bearing a π-extended phenanthridine (3,4-benzoquinoline) unit is presented. The proligand was isolated as the imidazolium salt of chloride (1•HCl), bromide (1•HBr), or hexafluorophosphate ...
Monofunctional platinum(ii) anticancer complexes based on multidentate phenanthridine-containing ligand frameworks
(Royal Society of Chemistry, 2020-04-20)
Phenanthriplatin is a leading preclinical anticancer Pt complex distinguished by a phenanthridine ligand that facilitates DNA-targeted covalent binding via intercalation. We report here that Pt(II) complexes incorporating ...
Catalytic C–H Bond Alkylation of Azoles with Alkyl Halides Mediated by Nickel(II) Complexes of Phenanthridine-Based N^N–^N Pincer Ligands
(American Chemical Society, 2020-04-24)
Ni(II) complexes supported by tridentate N^N–^N diarylamido pincer-type ligands have been demonstrated to act as active catalysts in the carbon–carbon bond forming alkylation of azoles using unactivated alkyl halides. Here, ...
