Embodiment 1
[0031] Add 1.23g of aminopropyltriethoxysilane dropwise to 50mL of absolute ethanol solution with 1.79g of magnesium chloride, adjust the pH to 10 with ammonia water, continue stirring at room temperature for 24h; centrifuge the obtained suspension , Wash the solid 3 times with anhydrous ethanol to remove the raw materials not participating in the reaction, and place the solid product in an oven at 60° C. to fully dry to obtain an amino functionalized organoclay.
[0032] Weigh 0.1 g of the amino-functionalized organoclay prepared in the previous step, add it to 10 mL of deionized water, and dissolve it ultrasonically; weigh 0.01 g of aggregation-inducing luminescent molecule BTPE and dissolve it in 10 mL of dimethyl sulfoxide solution. Mix the above two solutions, continue stirring at 80°C for 24 hours, and then cool to room temperature.
[0033] Add 100 mL of absolute ethanol to the above solution, stir for 5 min and then stand still. The obtained suspension was centrifuged, and...
Embodiment 2
[0035] Add 2.5g of N-aminoethyl-3-aminopropyltriethoxysilane dropwise to a 50mL absolute ethanol solution with 2.5g of terbium chloride dissolved, and adjust the pH to 12 with an aqueous sodium hydroxide solution at room temperature. Continue to stir for 10h; centrifuge the obtained suspension, wash the solid with absolute ethanol 3 times to remove the raw materials not participating in the reaction, place the solid product in an oven at 60℃ and fully dry it to obtain a diamino functionalized organoclay .
[0036] Weigh 0.1 g of the bisamino functionalized organoclay prepared in the previous step, add it to 15 mL of deionized water, and dissolve it ultrasonically; weigh 0.02 g of aggregation-inducing luminescent molecule CN-COOH and dissolve it in 15 mL of dimethyl sulfoxide solution. Mix the above two solutions, continue stirring at 80°C for 24 hours, and then cool to room temperature.
[0037] Add 100 mL of absolute ethanol to the above solution, stir for 10 min and then stand s...
Embodiment 3
[0039] Add 0.6g of 3-chloropropyltriethoxysilane dropwise to 50mL of absolute ethanol solution with 1.3g of calcium chloride dissolved in it, adjust the pH to 12 with potassium hydroxide aqueous solution, and continue to stir for 30h at room temperature; The obtained suspension was centrifuged, and the solid was washed 3 times with absolute ethanol to remove the raw materials that did not participate in the reaction. The solid product was placed in an oven at 60° C. and fully dried to obtain a chlorine-based functionalized organoclay.
[0040] Weigh 0.1 g of the prepared chlorine-based functionalized organoclay, add it to 10 mL of deionized water, and dissolve it ultrasonically; weigh 0.03 g of aggregation-inducing luminescent molecule TPE-OH and dissolve it in 20 mL of dimethyl sulfoxide solution. Mix the above two solutions, continue to stir at 70°C for 30h, and then cool to room temperature.
[0041] Add 100 mL of absolute ethanol to the above solution, stir for 10 min and then ...
