Embodiment 1
[0034] A kind of polymer nanoparticle preparation that can detect hypochlorous acid and copper ion, comprises the following steps:
[0035] (1) Preparation of product 1.
[0036] Dissolve PEO-TTC (0.2 mmol), styrene (36 mmol), AEMH (4 mmol) and azobisisobutyronitrile (0.057 mmol) in 4 mL of 1,4-dioxane, ice bath condition Under vacuum and nitrogen cycle three times. The temperature was raised to 90°C for 4 h. After the reaction was completed, it was precipitated with an appropriate amount of diethyl ether (30 mL), centrifuged, and dried in vacuo to obtain the desired product 1.
[0037] (2) Using the product prepared in step (1) and rhodamine B isothiocyanate to synthesize product 2.
[0038] Dissolve the product 1 (0.03 mmol) synthesized in step (1) and rhodamine B isothiocyanate (0.054 mmol) in DMF (5 mL), and place the mixed solution in the dark under N 2 Stir at room temperature for 24 h under protected conditions. After the reaction, most (85-95%) of DMF was removed by...
Embodiment 2
[0042] A kind of polymer nanoparticle preparation that can detect hypochlorous acid and copper ion, comprises the following steps:
[0043] (1) Preparation of product 1.
[0044] Dissolve PEO-TTC (0.2 mmol), styrene (34 mmol), AEMH (6 mmol) and azobisisobutyronitrile (0.057 mmol) in 4 mL of 1,4-dioxane, ice bath condition Under vacuum and nitrogen cycle three times. The temperature was raised to 90°C for 4 h. After the reaction was completed, it was precipitated with an appropriate amount of diethyl ether (30 mL), centrifuged, and dried in vacuo to obtain the desired product 1.
[0045] (2) Using the product prepared in step (1) and rhodamine B isothiocyanate to synthesize product 2.
[0046] Dissolve the product 1 (0.03 mmol) synthesized in step (1) and rhodamine B isothiocyanate (0.054 mmol) in DMF (5 mL), and place the mixed solution in the dark under N 2 Stir at room temperature for 24 h under protected conditions. After the reaction, most (85-95%) of DMF was removed by...
Embodiment 3
[0050] A kind of polymer nanoparticle preparation that can detect hypochlorous acid and copper ion, comprises the following steps:
[0051] (1) Preparation of product 1.
[0052] Dissolve PEO-TTC (0.2 mmol), styrene (38 mmol), AEMH (2 mmol) and azobisisobutyronitrile (0.057 mmol) in 4 mL of 1,4-dioxane, ice bath condition Under vacuum and nitrogen cycle three times. The temperature was raised to 90°C for 4 h. After the reaction, it was precipitated with an appropriate amount of diethyl ether (20 mL), centrifuged, and dried in vacuum to obtain the desired product 1.
[0053] (2) Using the product prepared in step (1) and rhodamine B isothiocyanate to synthesize product 2.
[0054] Dissolve the product 1 (0.03 mmol) synthesized in step (1) and rhodamine B isothiocyanate (0.054 mmol) in DMF (5 mL), and place the mixed solution in the dark and N 2 Stir at room temperature for 24 h under protected conditions. After the reaction, most (85-95%) of DMF was removed by rotary evapora...
