Embodiment

[0030] 1) Synthesis of compound TBT:

[0031] Add ice cubes and a small amount of water into the Dewar flask, put the three-necked flask into the Dewar flask, add 30 mL of chloroform solution into the three-necked flask, vacuumize the system with a double-pipe device, and then fill it with nitrogen, repeat three times. Then use a 10mL needle to extract 7mL of TfOH trifluoromethanesulfonate, pour it into the three-necked flask from the oblique rubber stopper of the three-necked flask, and then stir at room temperature for 2h. Add p-bromobenzonitrile (2.09g, 11.5mmol) and 30mL chloroform into the single-necked flask, first vacuumize the solution in the single-necked flask, then fill it with nitrogen, repeat three times, and use a constant pressure dropping funnel to remove the oxygen after deoxygenation. Add it dropwise into a three-necked flask, add 30mL of the solution dropwise for 25min, and react at room temperature for 48h after the dropwise addition. After the reaction wa...

Abstract

The invention discloses a preparation method of a phenazine group-containing microporous organic polymer, and catalytic applications of the phenazine group-containing microporous organic polymer on benzylamine oxidative coupling reaction, and belongs to the field of microporous organic polymer material preparation technologies and applications. According to the preparation method, 2, 4, 6-tri (4-bromophenyl)-1, 3, 5-triazine (TBT) and phenazine are taken as reaction monomers, and a conjugated microporous polymer (TPBP) with a relatively high specific surface area is prepared through a one-stepsimple Buchwald-Hartwig coupling substitution reaction. The phenazine units in the conjugated microporous polymer have good catalytic effect on oxidative coupling reaction of benzylamine molecules, and a plurality of times of recycling can be realized without losing catalytic activity, so that the application prospect is promising.

Description

technical field [0001] The invention belongs to the technical field of microporous organic polymer materials, and in particular relates to an organic polymer containing phenazine groups, a preparation method thereof, and a catalytic effect in benzylamine oxidative coupling reaction. Background technique [0002] Microporous organic polymers have been attracting extensive attention due to their favorable porosity, high surface area, tunable surface chemistry, light weight, and easy functionalization. Among them, porosity is considered to be one of the most important properties, and many applications have been developed based on this property, such as gas storage, catalysis, and adsorption. In terms of catalytic applications, microporous organic polymers, as heterogeneous catalysts, have been favored for a long time for their advantages of easy separation, simple post-treatment and recyclable use. [0003] Imine is an important component of many related biologically active he...
