METHOD OF PRODUCING CHEMOOPTICAL SENSOR IN FORM OF LAYER OF TWO-DIMENSIONAL STRUCTURE OF METAL-ORGANIC FRAMEWORK Russian patent published in 2024 - IPC C09K11/06 G01N21/17 H05B33/14 

FIELD: nano-optics.

SUBSTANCE: invention relates to nano-optics and can be used in designing chemoptical sensors, for example, for optical detection of vapours of toxic or hazardous chemical compounds at chemical industry enterprises. Method of producing a chemooptical sensor in form of 2D ZnTBAPy layer involves layering the MOF in a polar solvent by multiple freezing-thawing, wherein freezing is carried out in liquid nitrogen at a temperature of -196 °C and is characterized by the fact that the MOF freezing-thawing process is repeated 8-12 times, solvent is DMF, methanol or ethanol, and thawing is carried out in water heated from 70 to 85 °C. 2D ZnTBAPy is used in the form of a powder, the particles of which are dried before delamination, mixed with dimethylformamide and after the last thawing, a conclusion is made on obtaining a sensor.

EFFECT: obtaining thin layers of high surface area with high level of optical response when detecting toxic vapours.
