Embodiment 1
[0035] 1). Fully dissolve 4.4g resorcinol and 2.8mL acetaldehyde in 29.4mL ethanol with a volume concentration of 95% to form mixture A;
[0036] 2). Freeze the mixture A, and add 9.4 mL of hydrochloric acid with a volume concentration of 37% dropwise on the frozen mixture A to form a mixture B;
[0037] 3). Warm the mixture B to room temperature, and then heat it at 80°C for 24 hours. After cooling to room temperature, add 32.7 mL of deionized water to the mixture B to obtain a mixed solution;
[0038] 4). The mixed solution was placed at -20°C for 24 hours, and a yellow solid was obtained after filtration;
[0039] 5). Washing the yellow solid in the ice-ethanol aqueous solution prepared under the condition that the ratio of ethanol to water is 1:1, until the pH of the waste liquid is neutral, and a light yellow solid is obtained;
[0040] 6). The light yellow solid was vacuum-dried at a temperature of 100° C. for 16 hours to obtain a novel fluorescent compound with a yield...
Embodiment 2
[0042] 1). 6.6g of resorcinol and 2.8mL of acetaldehyde were fully dissolved in 32.3mL of ethanol with a volume concentration of 95% to form mixture A;

[0050] 2). Freeze the mixture A, and add 9 mL of hydrochloric acid with a volume concentration of 37% dropwise on the frozen mixture A to form a mixture B;
[0051] 3). Warm the mixture B to room temperature, and then heat it at 80°C for 24 hours. After cooling to room temperature, add 30 mL of deionized water to the mixture B to obtain a mixed solution;
[0052] 4). The mixed solution was placed at -20°C for 24 hours, and a yellow solid was obtained after filtration;
[0053] 5). Washing the yellow solid in an ice-ethanol aqueous solution prepared under the condition that the ratio of ethanol to water is 1:1, until the pH of the waste liquid is neutral, and a light yellow solid is obtained;
[0054] 6). The light yellow solid was vacuum-dried at a temperature of 100° C. for 16 hours to obtain a novel fluorescent compound with a ...
