Embodiment 1
[0023] (1) In a 25ml round bottom flask, add 9mg of sodium metal into 5ml of absolute ethanol and react for 15min.
[0024] (2) Add 30 mg of (2,5-dimercapto-1,3,4-thiadiazole) into the round bottom flask in step (1), and stir magnetically at room temperature for 2.5 hours.
[0025] (3) 21 mg of perchlorinated acenaphthylene was dissolved in 10 ml of toluene.
[0026] (4) Mix the solutions obtained in steps (2) and (3) in a 50ml round-bottomed flask with a stopper, and keep the temperature at 20°C for 48h.
[0027] (5) Pour out the solution after cooling to room temperature, and centrifuge with a 5ml centrifuge tube. The resulting solid precipitate is washed with toluene, ethanol, and water five times in sequence, and the precipitate is finally dispersed in ethanol.
[0028] (6) Mix 1 mg of microspheres washed in step 5 and 0.1 ml (aqueous solution with a concentration of 25.4 mmol / L) of chloroauric acid (HAuCl 4 ) mixed in 10ml of ethanol and water mixed reagent (wherein ethan...
Embodiment 2
[0032] (1) In a 25ml round bottom flask, add 9mg of sodium metal into 5ml of absolute ethanol and react for 30min.
[0033] (2) Add 30 mg of (2,5-dimercapto-1,3,4-thiadiazole) into the round bottom flask in step (1), and stir magnetically at room temperature for 2.5 hours.
[0034] (3) Dissolve 21 mg of perchloronaphthalene in 10 ml of toluene.
[0035] (4) Mix the solutions obtained in steps (2) and (3) into a 50ml round-bottomed flask with a stopper, and keep the temperature at 30°C for 24h.
[0036] (5) After cooling to room temperature, the solution was poured out, centrifuged with a 5ml centrifuge tube, and the obtained solid precipitate was washed with toluene, ethanol, and water 5 times respectively, and the precipitate was finally dispersed in ethanol.
[0037] (6) Mix 1 mg of the microspheres washed in Step 5 and 0.2 ml (aqueous solution with a concentration of 25.4 mmol / L) of chloroauric acid (HAuCl 4 ) mixed in 10ml of ethanol and water mixed reagent (wherein etha...
Embodiment 3
[0040] (1) In a 25ml round bottom flask, add 9mg of sodium metal into 5ml of absolute ethanol and react for 30min.
[0041] (2) Add 30 mg of (2,5-dimercapto-1,3,4-thiadiazole) into the round bottom flask in step (1), and stir magnetically at room temperature for 2.5 hours.
[0042] (3) 21 mg of perchlorinated acenaphthylene was dissolved in 10 ml of toluene.
[0043] (4) Mix the solutions obtained in steps (2) and (3) in a 50ml round-bottomed flask with a stopper, and keep the temperature at 40°C for 12h.
[0044] (5) After cooling to room temperature, the solution was poured out, centrifuged with a 5ml centrifuge tube, and the obtained solid precipitate was washed with toluene, ethanol, and water 5 times respectively, and the precipitate was finally dispersed in ethanol.
[0045] (6) Mix 1 mg of the microspheres washed in Step 5 and 0.2 ml (aqueous solution with a concentration of 25.4 mmol / L) of chloroauric acid (HAuCl 4 ) mixed in 10ml of ethanol and water mixed reagent (...
