Abstract

The invention discloses a perylene bisimide derivative nano-material and a preparation method and application thereof, the nano-material has specific selective response to sarin poison gas, and the nano-material is of a banded nano-structure formed by self-assembly of construction molecules through pi-pi stacking; according to the nanometer material, the construction molecules are subjected to crosslinking, interconnection or polymerization to form a net structure, the interconnected network structure provides a high-speed transmission channel for electron transfer among the molecules, rapid photoinduced electron transfer is further ensured, and the detection sensitivity of the nanometer material is improved; the high fluorescence quantum yield is beneficial to further improvement of the detection sensitivity, and the lowest detection limit of sarin poison gas is greatly reduced. The nano material has no fluorescent response to phosgene, soman poison gas, tower collapse poison gas, chlorine, mustard gas and the like, has good anti-interference capability, realizes specific and high-sensitivity detection of sarin poison gas, and has good application prospects.

Description

technical field [0001] The invention relates to the field of organic semiconductor nanomaterials, in particular to a perylene imide derivative nanomaterial and its preparation method and application. Background technique [0002] Sarin, also known as sarin poison gas, scientifically known as isopropyl meflodronate, is a class G nerve agent that can paralyze the central nervous system. It is a nerve paralyzing agent and is classified as a nerve agent by its injurious effect. It has a very faint fruity aroma, is a colorless transparent liquid, is easily mixed with water, and can be dissolved in organic solvents, and can easily penetrate into porous surfaces and painted surfaces. Sarin is the most volatile of all nerve paralyzing agents. It has a strong contraction effect on the human pupil. When sarin invades the human body in various ways, its toxic effect can damage nerve conduction. The incubation period of sarin is extremely short. When sarin is poisoned through the re...
