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...
