Tailoring dicobalt Pacman complexes of Schiff-base calixpyrroles towards dioxygen reduction catalysis.

چکیده
By modifying the mouth of a macrocyclic dicobalt Pacman complex, it is possible to both isolate new bridging-superoxo and hydroxyl complexes and to tune the reactivity of this system towards catalytic four-electron reduction of dioxygen to water.

Ligand modifications for tailoring the binuclear microenvironments in Schiff-base calixpyrrole pacman complexes.
The synthesis and structures of two new octadentate, Schiff-base calixpyrrole macrocycles are presented in which modifications at the meso-substituents (L(1)) or the aryl spacer between the two pyrrole-imine donor compartments (L(2)) are introduced. The outcomes of these changes are highlighted in the structures of binuclear Pacman complexes of these macrocycles, [M(2)(L(1))] and [M(2)(L(2))]. ...
متن کاملBinuclear cobalt complexes of Schiff-base calixpyrroles and their roles in the catalytic reduction of dioxygen.
The syntheses and characterization of a series of binuclear cobalt complexes of the octadentate Schiff-base calixpyrrole ligand L are described. The cobalt(II) complex [Co(2)(L)] was prepared by a transamination method and was found to adopt a wedged, Pac-man geometry in the solid state and in solution. Exposure of this compound to dioxygen resulted in the formation of a 90:10 mixture of the pe...
متن کاملDioxygen reduction catalyzed by dicobalt Pacman complexes
The development of fuel cell technologies for automotive use in particular is integral to clean and sustainable energy generation, and relies on catalysts to carry out fundamental chemical redox reactions at the electrodes. At present, the four-electron reduction of dioxygen to water that occurs at the cathode is the most problematic as it is catalysed by expensive Pt metal that requires consid...
متن کاملA macrocyclic approach to transition metal and uranyl Pacman complexes.
Multielectron redox chemistry involving small molecules such as O2, H2O, N2, CO2, and CH4 is intrinsic to the chemical challenges surrounding sustainable, low-carbon energy generation and exploitation. Compounds with more than one metal reaction site facilitate this chemistry by providing both unique binding environments and combined redox equivalents. However, controlling the aggregation of me...
متن کاملSynthesis and Characterization of Metal Complexes of Cu(II), Ni(II), Zn(II), Co(II), Mn(II) and Cd(II) with Tetradentate Schiff Bases
Tetradentate Schiff bases with a N2O2 donor atom set are well known to coordinate with various metal ions, and this has attracted the interest of many authors1−12. Complexes of Schiff base ligands have been studied for their dioxygen untake and oxidative catalysis. Furthermore, complexes of transition metals(II), which involve derivatives of salicyldhyde and diamine, have received considerable ...
