[0034]The present invention also provides a method for preparing a cross-shaped semiconductor material for explosive detection, which includes 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 perform reflux 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 a role of phase transfer catalysis in the reaction, and promotes the reaction of the R-pyrrole compound with the R`-furan of the aldehyde group or the R`-pyridine containing the aldehyde group. It should be noted that the crude solid reaction product obtained in this step is a mixture of the target product and its isomers.
[0036]S2: Take the solid reaction crude product prepared in step S1 and catalyst II and add the...

[0052]Example 1
[0053]A cross-shaped semiconductor material for explosive detection, specifically compound M1 with the following structure,
[0054]
[0055]First add the reaction raw materials indole (0.02mol) and tetrabutylammonium iodide (0.002mol) solution into a two-necked reaction flask (250ml) containing acetonitrile solvent (50ml), and then add pyridine-2-carbaldehyde (0.02mol) mol) and HBF4(0.002mol), the reaction temperature is controlled to 80°C, and the reflux reaction is performed for 10 hours. After the reaction is finished and the temperature is lowered, the reaction mixture is filtered, washed with acetonitrile solution (50 ml), and dried to obtain a crude solid reaction product.
[0056]Add acetonitrile solution (50ml) and I2(0.002mol), control the reaction temperature to 80°C and continue the reflux reaction for 14h. After the reaction is finished and the temperature is lowered, the reaction mixture is poured into water. After suction filtration, another crude solid product ...
