Phenanthridine-Containing Pincer-like Amido Complexes of Nickel, Palladium, and Platinum
(American Chemical Society, 2017-03-07)
Proligands based on bis(8-quinolinyl)amine (L1) were prepared containing one (L2) and two (L3) benzo-fused N-heterocyclic phenanthridinyl (3,4-benzoquinolinyl) units. Taken as a series, L1–L3 provides a ligand template for ...
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 ...
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 ...
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 ...
Iron(II) Coordination Complexes with Panchromatic Absorption and Nanosecond Charge-Transfer Excited State Lifetimes
(Nature Publishing Group, 2019-11-18)
Replacing current benchmark rare-element photosensitizers with ones based on abundant and low-cost metals such as iron would help facilitate the large-scale implementation of solar energy conversion. To do so, the ability ...
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+ ...
