Synthesis and Reactivity of Bimetallic Systems Tethered with a 4,5-Diaminoxanthene Linker

Reactivity Profile of a Formally Dicobalt(0) Complex Bound by a Redox-Active Macrocycle

“…Rigid aromatic groups are popular tethers, with xanthyl and naphthyl groups often used to link together well-studied ligands such as β-diketiminates or pyridyldiimines (PDI). , Depending on the tether, these complexes often have substantial vertical flexibility while still maintaining a cofacial arrangement between the metal chelates . An example of this for cobalt, which will be the continued focus herein, comes from the Groysman group, who have tethered PDI moieties together with a wide assortment of linkers. , …”

“…8 An example of this for cobalt, which will be the continued focus herein, comes from the Groysman group, who have tethered PDI moieties together with a wide assortment of linkers. 9,10 We have recently sought to marry the two design principles discussed above by using a bis-pyridyldiimine ( 3 PDI 2 ) scaffold to create redox-active and geometrically flexible dinucleating macrocycles. Prior studies have shown that these 3 PDI 2 macrocycles adopt a variety of geometries 11,12 and ligand reduction states.…”

Cartoon Weapons Industry: Prejudicial News Reports and the Terrorising of Magazines

“…For Australasia, we ask, for example, what led to Brenton Tarrant smirking and flashing a hate symbol 1 as his lawyer submitted his plea of not guilty for the charge of terrorism and the murder of 51 people in Christchurch, New Zealand (Hollingsworth, 2019). The ‘OK’ symbol that the Islamophobic, manifesto-writing, Brevik-worshipping Australian formed with his hand for the camera is associated with the related media frames, the election campaigns of former US President Donald Trump, the phenomenon of far right-wing trolling, and fictional figures of ‘fun’ like Pepe the Frog.…”
