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.

[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.

Description

technical field [0001] The invention belongs to the technical field of fluorescent materials. More specifically, it relates to an antimony pentachloride fluorescent compound, a crystal and a preparation method and application thereof. Background technique [0002] Organic-inorganic hybrid metal halides have attracted extensive attention worldwide in recent years due to their bright emission, tunable photoluminescence wavelengths, and convenient synthesis methods. At present, organic-inorganic hybrid metal halides have become a new type of light-emitting materials, which are used in many fields, including photovoltaics, lasers, and light-emitting diodes (LEDs). Moreover, in organic-inorganic hybrid metal halide materials, large organic cations separate the metal halides to form a good "host-guest" structure. This zero-dimensional (0D) metal halide with a "host-guest" system These materials provide a good platform for rational structural tunability and photoluminescence modu...
