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 ...
Synthesis of Pyridines, Quinolines, and Pyrimidines via Acceptorless Dehydrogenative Coupling Catalyzed by a Simple Bidentate P^N Ligand Supported Ru Complex
(American Chemical Society, 2020-03-30)
A ruthenium hydrido chloride complex (1) supported by a simple, heteroleptic bidentate P^N ligand (L1) containing a diarylphosphine and a benzannulated phenanthridine donor arm is reported. In the presence of base, complex ...
Redox non-innocent bis(2,6-diimine-pyridine) ligand–iron complexes as anolytes for flow battery applications
(Royal Society of Chemistry, 2017-11-13)
Diiminepyridines are a well-known class of “non-innocent” ligands that confer additional redox activity to coordination complexes beyond metal-centred oxidation/reduction. Here, we demonstrate that metal coordination ...
Luminescent Platinum(II) Complexes of N^N–^N Amido Ligands with Benzannulated N-Heterocyclic Donor Arms: Quinolines Offer Unexpectedly Deeper Red Phosphorescence than Phenanthridines
(American Chemical Society, 2019-10-22)
A platform for investigating the impact of π-extension in benzannulated, anionic pincer-type N^N–^N-coordinating amido ligands and their Pt(II) complexes is presented. Based on bis(8-quinolinyl)amine, symmetric and asymmetric ...
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 ...
Site-Selective Benzannulation of N-Heterocycles in Bidentate Ligands Leads to Blue-Shifted Emission from [(P^N)Cu]2(μ-X)2 Dimers
(American Chemical Society, 2018-04-12)
Benzannulated bidentate pyridine/phosphine (P^N) ligands bearing quinoline or phenanthridine (3,4-benzoquinoline) units have been prepared, along with their halide-bridged, dimeric Cu(I) complexes of the form [(P^N)Cu]2(μ-X)2. ...
Exploiting synergy between ligand design and counterion interactions to boost room temperature phosphorescence from Cu(i) compounds
(Royal Society of Chemistry, 2019-01-16)
The structural and photophysical properties of three sets of luminescent copper complexes of the form [(P^N)2Cu]X are presented. Here, P^N represents a bidentate ligand based on phenanthridine (3,4-benzoquinoline) incorporating ...
Catalytic Synthesis of Luminescent Pyrimidines via Acceptor-less Dehydrogenative Coupling
(American Chemical Society, 2020-10-23)
A simple catalytic synthesis of luminescent pyrimidines from benzamidines and alcohols is reported. These one-pot, acceptor-less dehydrogenative coupling reactions are catalyzed by a ruthenium hydrido chloride complex (1), ...
