Embodiment

[0016] (1) Take 3.92g 3,4,9,10-perylenetetracarboxylic dianhydride (PTCDA), 9.68g trishydroxymethylaminomethane (THAM), 1.83g anhydrous zinc acetate ((CH 3 COO) 2 Zn) and 100ml N-methylpyrrolidone (NMP) were added to a 250ml three-port reactor, heated to 80°C under a nitrogen atmosphere, stirred and mixed for 15 minutes, then continued to heat up to 155°C and stirred for 16 hours to obtain a dark purple mixture.

[0017] (2) Suction filter the deep purple solution prepared in step (1), wash the filtrate 4 times with ethanol, and then put it in a vacuum oven at 50°C to dry for 10 hours, and the obtained purple powder is hydroxylated perylene imide, labeled as PBI.

[0018] The hydroxylated peryleneimide prepared in this example is applied to the synthesis of high-performance shape-memory polyurethane materials, and the specific steps are as follows:

[0019] (1) Put 2.0 g of polycaprolactone diol with a weight-average molecular weight of 1000 into a round-bottomed flask, heat...

Abstract

The invention discloses a preparation method of hydroxylated perylene imide and application thereof. The preparation method comprises the following steps: weighing perylene-3,4,9,10-tetracarboxylic dianhydride, trihydroxymethyl aminomethane and zinc acetate in mole ratio of 1 to (6-10) to 1 as raw materials, adding the raw materials into a reactor filled with N-methyl pyrrolidone, heating to 75-85 DEG C under the nitrogen atmosphere, stirring and mixing for 15min, and then continuously warming to 150-160 DEG C, stirring and reacting for 15-17h to prepare a dark purple mixed liquid; leaching the deep purple mixed liquid, firstly washing the filtered substance for 3-5 times by use of ethanol, and then placing the filtered substance in a vacuum drying oven at 45-55 DEG C and drying for 8-12h to obtain the purple powder, namely, hydroxylated perylene imide. Hydroxylated perylene imide can be applied to the technical field of synthesis of high-performance shape-memory polyurethane material. According to the method disclosed by the invention, the operation is simple, the used reagent raw materials are conventional chemical raw materials, the cost is low, and the method is convenient for large-scale popularization; and the prepared hydroxylated perylene imide can be used for preparing the shape-memory polyurethane material, and further broadens other application fields of perylene besides the dye field.

Description
