Embodiment 1

[0045] Add 2.14g of 3,4,9,10-perylenetetracarboxylic dianhydride (PTDA) (M=392) to the 18mL concentrated (98%) H 2 SO 4 (M=98,1.836g / mL) in a three-necked flask, vibrate with 35Hz ultrasonic for 10min, then place it on a heat-collecting thermostatic magnetic stirrer and add a condenser. After stirring at room temperature for 6h, adjust the temperature to 80 ℃, reflux reaction, add 0.053gI in the meantime 2 (M=127) As a catalyst, about 0.577 mL (3.12 g / mL) of liquid bromine (M=160) was slowly added dropwise into it using a constant pressure dropping funnel. After 24 hours of reaction, the reaction solution was diluted with distilled water to 60% concentrated sulfuric acid and filtered with suction to obtain a filter cake. The filter cake was placed in a vacuum drying oven at 90°C for 24 hours. The filter cake mainly contains the aforementioned three compounds a, b, and c, where a:b:c=7:2:1.

Abstract

The invention provides a graphene oxide/perylene bisimide donor-receptor composite material. A preparation method of the graphene oxide/perylene bisimide donor-receptor composite material is mainly characterized in that 3,4,9,10-perylenetetracarboxylic dianhydride is taken as a raw material, and a perylene bisimide derivative with low LOMO energy level and excellent photoelectric property is synthesized through bromination, amidation and nucleophilic substitution; then the graphene oxide/perylene bisimide organic-inorganic hybrid donor-receptor composite material is synthesized on the basis of nucleophilic substitution. The raw materials of the composite material are easy to obtain and low in cost, and the reaction yield is high. Graphene oxide has large specific surface area and contains oxygen-containing functional groups which can produce strong actions with metal ions, so that the composite material has high sensitivity and selective recognition on divalent copper metal ions in the environment and has pH sensitivity.

Description

Technical field [0001] The invention relates to an organic and inorganic hybrid material and a preparation method thereof. Background technique: [0002] In recent years, clean water sources have been seriously polluted by organic matter, heavy metal ions, acids and alkalis. Among them, divalent copper ions have a great impact on human health. Scientific experiments have confirmed that when a large amount of heavy metals remain in the human body, it is easy to The organs in the body cause a burden, especially the liver and gallbladder. When these two organs have problems, the metabolism of the body will be disturbed, and even liver cirrhosis and liver ascites. Therefore, in order to be able to easily detect the water in the source The concentration of divalent copper ions protects people's lives and health. The research and development of materials that can absorb pollution and detect divalent copper ions have become a hot spot in recent years. [0003] Since graphene oxide-based ...
