| titleOfInvention | A fluorescent probe for recognizing thiocyanate and its preparation method and detection method |
| abstract | The invention discloses a fluorescent probe for recognizing thiocyanate, a preparation method and a detection method thereof. Its preparation method is (1) adding 1,2-bis-(4-bromophenyl)-ethylene, 4-pyridine boronic acid and palladium acetate into triethylamine and mixing, reacting to obtain product A; (2) mixing product A Completely dissolve into a black suspension with dichloromethane to obtain product B; (3) wash product B to obtain product C; (4) leave product C to stand and separate layers, and after separating the bottom dichloromethane layer, Dry, spin dry, and finally recrystallize with ethanol to obtain product D; (5) add product D to N,N-dimethylformamide to dissolve, then add 1-bromooctane, heat to 75-85°C, and react After 20-36 hours, diethyl ether was added to the reaction solution until it was completely precipitated, filtered with suction, washed twice with diethyl ether, and dried to obtain a fluorescent probe. It is used to detect thiocyanate in water system. The probe of the invention can detect thiocyanate, and has low detection cost, simple operation, visible structure, high sensitivity and good selectivity. |
