Nano material based on perylene bisimide as well as preparation method and application of nano material

Abstract

The invention discloses a nanometer material based on perylene bisimide and a preparation method and application of the nanometer material. The nanometer material has specific selective response shuttle man and is of a strip-shaped nanometer structure formed by self-assembly of construction molecules through pi-pi stacking; the structural formula of the building molecules is as follows: the nano material is of a radial network structure, and the interconnected network structure provides a high-speed transmission channel for electron transfer among molecules, so that the rapid proceeding of photoinduced electron transfer is effectively ensured; the high fluorescence quantum yield is beneficial to further improvement of the detection sensitivity, and the lowest detection limit of the soman poison gas is greatly reduced. And the nano material has no fluorescent response to phosgene, sarin poison gas, tower collapse poison gas, chlorine gas, mustard gas and the like, has good anti-interference capability, realizes detection of shuttle man specificity and high sensitivity, and has good application prospects.

Description

technical field [0001] The invention relates to the field of organic semiconductor nanomaterials, in particular to a peryleneimide-based nanomaterial and its preparation method and application. Background technique [0002] Soman is a colorless liquid with a faint fruity aroma, moderate volatility, and its chemical name is isoethyl methylfluorophosphate. In 1944, Dr. Richard Kuhn, a German Nobel laureate, synthesized soman for the first time. The inhalation toxicity of soman is 2-4 times that of sarin, and the skin toxicity is 5-10 times that of sarin. It can be inhaled through the respiratory tract, can also kill humans and animals through skin absorption, or poison food and water sources, and enter the body through the digestive tract. If a person inhales a few mouthfuls of high-concentration soman vapor, he can be fatal within a minute. Another characteristic of Soman is that it has a quick poisoning effect and no specific antidote, so it is known as "the most difficul...
