Specification
The chemical interaction between 5,6-diamino-1,10-phenanthroline (dap) and diphosphine ligands xantphos [9,9-dimethyl-4,5-bis(diphenylphosphino)-9H-xanthene (xantphos)] or bis[(2-diphenylphosphino)phenyl] ether (POP) with [Cu(MeCN)4]ClO4 resulted in the synthesis of mononuclear complex [Cu(dap)(PP)]ClO4 (2a) and binuclear complexes [Cu2(μ-pdi)(PP)2](ClO4)2 (2b) and [Cu2(μ-ttpd)(xantphos)2](ClO4)2 (1c).
Synthetic routes of the Cu(I) complexes
· The synthetic procedure for these Cu(I) complexes began with the reaction of 5,6-diamino-1,10-phenanthroline (dap), xantphos or POP, and Cu(CH3CN)4ClO4 in a 1: Mononuclear complexes 1a or 2a form when the reaction between 5,6-diamino-1,10-phenanthroline (dap), xantphos or POP and Cu(CH3CN)4ClO4 occurs at a 1:1:1 stoichiometric ratio under conditions lacking moisture and oxygen.
· Experiments demonstrated that complexes 1a and 2a can form even when exposed to oxygen. Increasing the stoichiometric ratio to 1: The formation of binuclear complexes 1b and 2b with pdi occurred when the mixture at a 1:2:2 ratio crystallized through air diffusion.
· Additionally, combining dap, xantphos, and Cu(CH3CN)4ClO4 in a 1: The combination of dap and xantphos plus Cu(CH3CN)4ClO4 in a 2:2 ratio with a dap solution under aerobic conditions through diffusion crystallization produced complex 1c and complex 1b.
A non-precious metal catalyst (NPMC) for oxygen reduction reaction was prepared by surface modification of carbon black (Black Pearls 2000, BP) with 5,6-diamino-1,10-phenanthroline (aphen) via diazo and benzimidazole coupling chemistry. The prepared catalysts were highly active for oxygen reduction reaction (ORR) by introduction of Fe and pyrolysis at 700°C in NH3/N2 atmosphere.
· Diazonium Coupling Method
200 mg of BP was mixed with 25 mg of aphen (1 equivalent), along with 4 equivalents of concentrated sulfuric acid and 2 equivalents of sodium nitrite. This reaction converts the amino groups of aphen into diazonium groups, which then interact with the carbon surface. After stirring the mixture at room temperature for 30 minutes, collected the modified carbon through suction filtration before washing it with water and drying it overnight at 100 °C then grinding it into a fine powder. This product will be referred to as BP-D.
· Benzimidazole Coupling Method
In a separate procedure, 25 mg of aphen and 100 mg of BP were dissolved in 25 mL of 4M HCl and refluxed for 24 hours. The resulting sample was collected via suction filtration, washed with water, acetone, and methanol, dried overnight at 100 °C, and then ground to a fine powder. This product will be referred to as BP-B.
