Embodiment 1
[0032] Example 1: Preparation C 60 (NCH 2 CH 2 OCH 2 CH 2 Oh) 8 -Mn complex
[0033] 360mg C 60 with liquid N 3 CH 2 CH 2 OCH 2 CH 2 OH is sequentially fed into the three-necked reaction flask according to the stoichiometric ratio (molar ratio) of 1:100, protected by nitrogen, mechanically stirred, and controlled at a heating rate of 1°C / min, slowly rising to 120°C, keeping the temperature for 24 hours, stopping the reaction, and cooling the product to room temperature Dissolve in 500ml of water, filter, concentrate, dialyze with a molecular weight cut-off 500 dialysis bag, filter again, freeze-dry to obtain solidified fullerene-based nano-ligand 1; mix 0.1544g of fullerene-based nano-ligand 1 with 0.186g of four Hydrated manganese acetate was dispersed in 200ml of methanol according to the molar ratio of 1:10, isolated from the air, refluxed for 12 hours, terminated the reaction, distilled off the methanol and redissolved in water, dialyzed in a dialysis bag with a...
Embodiment 2
[0039] Example 2: Preparation C 70 (NCH 2 CH 2 OCH 2 CH 2 Oh) 10 -Mn complex
[0040] With reference to embodiment 1, 420mg C 70 with liquid N 3 CH 2 CH 2 OCH 2 CH 2 OH is sequentially fed into the three-necked reaction flask according to the stoichiometric ratio (molar ratio) of 1:100, and the rest of the conditions are the same as in Example 1 of the present invention to obtain the pure fullerene-based nano ligand 2 solid product, and its average molecular formula is characterized by thermogravimetric analysis: C 70 (NCH 2 CH 2 OCH 2 CH 2 Oh) 10 .
