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. ...
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 ...
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), ...
Electrochemical Reduction of Carbon Dioxide to Methanol in the Presence of Benzannulated Dihydropyridine Additives
(American Chemical Society, 2017-02-01)
Dihydropyridines (DHPs) have been postulated as active intermediates in the pyridine-mediated electrochemical conversion of CO2 to methanol; however, the ability of isolated DHPs to facilitate methanol production in a ...
Monomeric zinc(II) amide complexes supported by bidentate, benzannulated phenanthridine amido ligands
(Elsevier, 2019-03-15)
The first examples of homoleptic zinc amides (1-Zn and 2-Zn) supported by chelating, benzannulated 4-amidophenanthridine ligands (L1, L2) are reported. The organometallic compounds were characterized fully both in solution ...
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 ...
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 ...
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 ...
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, ...
