Compound material constructed by molecular engram and fluorescent conjugated polymer, preparation and application

[0033] Embodiment 1 Synthesis process is as follows:

[0034] Side chain (12 carbons) TNT-sensitive fluorescent conjugated polymer containing molecularly imprinted active monomer 1mmol (see structure Figure 4 ), acrylamide (1mmol), di(methacrylic acid)-ethylene glycol ester (4mmol), explosive template molecules (including Octogen, RDX, nitroglycerin, the ratio of the three is 1:1:1 , a total of 0.018mmol), add 0.012mmol of benzoyl peroxide, dissolve in 5mL of toluene, and heat to 60-70°C to react for 6 hours. The resulting polymer was precipitated, centrifuged, and the polymer was washed successively with toluene and ethanol. Soxhlet extractor extracts and removes template molecules to obtain a light yellow composite polymer with a yield of 85%.

[0035] Embodiment 2 (change crosslinking monomer), synthetic process is as follows:

[0036] 1 mmol of TNT-sensitive fluorescent conjugated polymers with double side chains (12 carbons) containing molecularly imprinted active monomers (see Figure 4 ), acrylic acid (1mmol), di(methacrylic acid)-ethylene glycol ester (4mmol), explosive template molecules (including Octogen, RDX, nitroglycerin, the ratio of the three is 1:1:1, 0.018mmol in total), add 0.012mmol of benzoyl peroxide, dissolve in 5mL of toluene, and heat to 60-70°C to react for 6 hours. The resulting polymer was precipitated, centrifuged, and the polymer was washed successively with toluene and ethanol. Soxhlet extractor extracts and removes template molecules to obtain a light yellow composite polymer with a yield of 87%.

[0037] Embodiment 3 (carbon chain length changes)

[0038] 1 mmol of TNT-sensitive fluorescent conjugated polymers with double side chains (6 carbons) containing molecularly imprinted active monomers (see Figure 4 ), acrylamide (1mmol), di(methacrylic acid)-ethylene glycol ester (4mmol), explosive template molecules (including Octogen, RDX, nitroglycerin, the ratio of the three is 1:1:1 , a total of 0.018mmol), add 0.012mmol of benzoyl peroxide, dissolve in 5mL of toluene, and heat to 60-70°C to react for 6 hours. The resulting polymer was precipitated, centrifuged, and the polymer was washed successively with toluene and ethanol. Soxhlet extractor extracts and removes template molecules to obtain a light yellow composite polymer with a yield of 90%. The product is less soluble in common solvents such as DMF and DMSO. Not suitable for further device preparation.
