Embodiment 1
[0076] Embodiment 1 A kind of antimony pentachloride fluorescent compound
[0077] The preparation steps of the antimony pentachloride fluorescent compound (1#) are as follows:
[0078] S1. Weigh 0.1 mmol of antimony trichloride (easy to deliquescence and need to be quickly) in a small glass bottle, add 2 mL of acetone to dissolve, and obtain solution A;
[0079] S2. Weigh 0.2 mmol of tetramethylammonium chloride in a small glass bottle, add 3 mL of acetone to dissolve, and obtain solution B;
[0080] S3. The solution B obtained in step S2 was carefully added dropwise to the solution A obtained in step S1, heated at 50°C and stirred for 8 hours to obtain white crystals, namely compound 1#, with a yield of 42%.
[0081]
[0082] The obtained compound 1# emits bright yellow light under ultraviolet irradiation, and the yellow light disappears after being contacted with air for 5 minutes. Daily storage needs to be isolated from air.

Embodiment 2
[0085] Embodiment 2 A kind of antimony pentachloride fluorescent compound
[0086] The preparation steps of the antimony pentachloride fluorescent compound (2#) are as follows:
[0087] S1. Weigh 0.1 mmol of antimony trichloride (easy to deliquescence and need to be quickly) in a small glass bottle, add 2 mL of acetone to dissolve, and obtain solution A;
[0088] S2. Weigh 0.2 mmol of tetraethylammonium chloride in a small glass bottle, add 18 mL of acetone to dissolve, and obtain solution B;
[0089] S3. Carefully drop the solution B obtained in step S2 into the solution A obtained in step S1, heat at 50°C and stir for 2 days, loosen the cap and slowly evaporate two-thirds of the solvent to obtain large white crystals, namely As compound 2#, yield: 42.50%.
[0090]
[0091] The obtained compound 2# emits bright yellow light under ultraviolet irradiation, has good wet stability, and still produces bright yellow light after being placed in the air for 3 months.

Embodiment 3
[0101] Embodiment 3 A kind of antimony pentachloride fluorescent compound
[0102] The preparation steps of the antimony pentachloride fluorescent compound (3#) are as follows:
[0103] S1. Weigh 0.1 mmol of antimony trichloride (easy to deliquescence and need to be quickly) in a small glass bottle, add 2 mL of acetone to dissolve, and obtain solution A;
[0104] S2. Weigh 0.25 mmol of tetrapropylammonium chloride in a small glass bottle, add 3 mL of acetone to dissolve, and obtain solution B;
[0105] S3. The solution B obtained in step S2 was carefully added dropwise to the solution A obtained in step S1, heated at 50 °C and stirred for 24 hours, and then placed at room temperature for one day to obtain colorless crystals, namely compound 3#, yield: 43 %.
[0106]
[0107] The obtained compound 3# emits bright yellow light under ultraviolet irradiation, has good wet stability, and still produces bright yellow light after being placed in the air for 3 months.
