Preparation method of terephthalaldehyde 2-amino-4-methylphenol Schiff base single crystal

The invention discloses a preparation method of a novel p-phthalaldehyde condensed 2-amino-4-methylphenol Schiff base single crystal. The method comprises the following steps: weighing 1 mmol of terephthalaldehyde (TPA) and dissolving the TPA into 5 mL of N',N'-dimethylformamide; adding 25 mL of absolute methanol, completely dissolving the components, adding 2 mmol of 2-amino-4-methylphenol (MPA),sealing the reactor with a sealing film, carrying out an ultrasonic reaction for a period of time, carrying out standing treatment at room temperature for 2-3 days, carrying out reduced pressure suction filtration, washing the reaction product with absolute methanol, and drying the reaction product with CaCl2 in vacuum to obtain yellow Schiff base single crystals. The compound has good optical properties, can be used as a fluorescent probe for tumor cell imaging, and is expected to expand the application range of Schiff base fluorescent dyes. 本发明公开一种新型对苯二甲醛缩2-氨基-4-甲基苯酚席夫碱单晶的制备方法，包括如下步骤：称取1 mmol对苯二甲醛(TPA)溶于5 mL N´-N´-
