Abstract

The invention discloses a one-dimensional organic semiconductor nano-material with fluorescence response to soman as well as a preparation method and application thereof. The nano-material is of a strip-shaped nano-structure formed by self-assembly of construction molecules through pi-pi stacking; the one-dimensional organic semiconductor nanomaterial line prepared by the invention has the characteristics of high fluorescence quantum yield, large surface area and the like, has no fluorescence response to phosgene, sarin poison gas, tower collapse poison gas, chlorine, mustard gas and the like, and has good anti-interference capability; the method realizes the detection of the soman specificity and high sensitivity, and has a good application prospect.

Description

technical field [0001] The invention relates to the field of organic semiconductor nanometer materials, in particular to a one-dimensional organic semiconductor nanometer material with fluorescence response to soman. 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 know...
