Abstract

The invention discloses a fluorescent sensor film preparation method based on a perylene diimide cholesterol derivative. According to the invention, cholesterol-modified perylene diimide is coated on the surface of a glass substrate, such that a fluorescent sensor film is prepared. With the film, sensitive detections upon organic amine gas can be realized. The method provided by the invention is advantaged by simple operation and mild reaction condition. With the method, prepared fluorescent sensor films are advantaged in good stability, long service life, and high sensitivity. The fluorescent sensor films are excellent organic amine gas sensor films. When the films are used in combination with commercial fluorescent devices, sensitive detections upon environmental organic amine can be realized. Also, the sensor films can be prepared into devices, and developed into special organic amine detection devices.

Description

technical field

[0001] The invention belongs to the technical field of small-molecule fluorescent sensing film materials, and in particular relates to peryleneimide cholesterol derivative fluorescent sensing films sensitive to organic amines. Background technique

[0002] Organic amines are organic derivatives of ammonia. One or more of the hydrogen atoms in ammonia are replaced by alkyl or aryl groups. They are a typical source of odor pollution after organic sulfides. The survey found that amine components are produced in industrial production and animal and plant corruption in many industries, such as chemical factories, pharmaceutical factories, leather factories, meat processing factories, poultry farms and aquatic product storage yards, garbage bins, sewers, etc. All can be regarded as the source of amine odorous substances, and organic amines also play a very important role in industrial production. Organic amines are volatile and highly carcinogenic. Therefore, thei...
