preparation example Construction

[0034] The present invention also provides a method for preparing a cross-shaped semiconductor material used for explosive detection, comprising the following steps:

[0035]S1: Add R-pyrrole compound and alkylamine salt to organic solvent I, continue to add R`-furan containing aldehyde group or R`-pyridine containing aldehyde group, and catalyst I, control the temperature, and reflux Reaction, after the reaction is completed and the temperature is lowered, the reaction mixture is filtered and dried to obtain a solid reaction crude product. Among them, the alkylamine salt plays the role of phase transfer catalysis in the reaction, and promotes the reaction of R-pyrrole compound with aldehyde-based R'-furan or aldehyde-containing R'-pyridine. It should be noted that the solid reaction crude product obtained in this step is a mixture of the target product and its isomers.

[0036] S2: Take the solid reaction crude product and catalyst II prepared in step S1 and add them to orga...

Description

【Technical field】 [0001] The invention relates to the technical field of photoelectric materials, in particular to a cross-shaped semiconductor material used for explosive detection and its preparation method and application. 【Background technique】 [0002] The adverse effects of explosives on national defense security, ecological environment and human health have aroused widespread concern. Traditional detection methods for explosives mainly include detection methods such as chromatography, spectroscopy and mass spectrometry. Although the chromatographic method has good separation effect and detection sensitivity, its separation speed is slow and it is difficult to quickly characterize it. The spectroscopic method is small in size, but it is not perfect for the multi-component analysis of explosives. Mass spectrometry realizes multi-component analysis, with high sensitivity, low false alarm rate, and fast analysis speed, but the equipment is heavy and inconvenient to carr...
