All reagents were used
without further purification unless otherwise mentioned. Bisphenol
A (99+%), boron trifluoride etherate, methyl iodide, anhydrous tetrahydrofuran
(THF), tert-butyl nitrite, sodium chloride, copper(I)
chloride, potassium carbonate (K2CO3, 99+%),
benzyl chloride, TMHD, sodium iodide, cesium carbonate, and anhydrous
NMP 99% were purchased from Sigma-Aldrich Chemical Co. and used as
received. Hexane, anhydrous diethyl ether, anhydrous sodium thiosulfate,
methylene chloride stabilized, sodium hydroxide (97%), toluene, methanol,
ethyl acetate, and 37% hydrochloric acid were purchased from Fisher
Chemicals and used without further modification. Acetonitrile was
purchased from Spectrum and used without further modification. Sodium
sulfate was purchased from Alfa Aesar and used without further modification.
All solvents were dried and purified by using the standard procedures.

Synthesis of Tin and Cobalt Nanoparticles

To prepare Sn NPs, a solution of NaBH 4 (96 mmol, 98%, ACBR) in anhydrous 1-methyl-2-pyrrolidone (NMP, 85 mL, 99.5%, Fisher BioReagents) was heated to 60 °C under flowing N 2 . Then, a solution of SnCl 2 (1 mmol, ≥99%, Alfa Aesar) in anhydrous NMP (3 mL) was injected and the reaction mixture was immediately cooled to room temperature using a water-ice bath. To prepare Co NPs, a NaBH 4 solution in anhydrous NMP (32 mmol in 15 mL) was heated to 150 °C under flowing N 2 , followed by the injection of CoCl 2 (8 mmol, ≥98%, Sigma-Aldrich) and immediate cooling to room temperature using a water-ice bath. The obtained Co NPs and Sn NPs were purified by washing once with dimethyl sulfoxide and then two times with water after separation from the supernatant by centrifugation. Finally, the reaction product was dried under vacuum at room temperature.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
