Embodiment 1
[0041] (1) Add 6.73g of 1,6-hexamethylene diisocyanate (40.00mmol) in dichloromethane solution to the round bottom flask connected with mechanical stirring, reflux condenser and inert protection device, then add 90.00g of bis(3- aminopropyl) terminated polydimethylsiloxane (30.00mmol) in dichloromethane and 1.09g 2,6-diaminopyridine (10.00mmol) in dimethyl sulfoxide; their solid content is 20%. Raise the reaction temperature to 60° C., and react for 12 hours under the protection of nitrogen to obtain a polysiloxane block copolymer containing pyridine ligands. figure 2 Shown is the product polysiloxane block copolymer containing pyridine ligands (a) and starting material 1,6-hexamethylene diisocyanate (c), bis(3-aminopropyl) terminated polydimethylsiloxane (b), IR characterization of 2,6-diaminopyridine (d). It can be seen from the figure that Si-O-Si and Si-C peaks and pyridine ligand peaks are clearly observed in (a) (the position indicated by * in the figure), which show...
Embodiment 2
[0045] Except that 0.90g ferric chloride hexahydrate / dehydrated ethanol solution (3.33mmol) is replaced with 0.54g ferric chloride hexahydrate / dehydrated ethanol solution (2.00mmol) in step 2, all the other are identical with embodiment 1, and product is named after PDMS-HDA@Fe-1 / 5.
Embodiment 3
[0047] Except that 0.90g ferric chloride hexahydrate / dehydrated ethanol solution (3.33mmol) is replaced by 2.70g ferric chloride hexahydrate / dehydrated ethanol solution (10.00mmol) in step 2, all the other are identical with embodiment 1, and product is named after PDMS-HDA@Fe-1 / 1.
