Fluorescent silane layers for the detection of explosives

摘要

A detection reagent for an analyte comprising an NO _x group, wherein the detection reagent comprises an arylamine, and a structural formula of the arylamine is selected from the structural formulas 1, 2 or 3: or according to the formulas 4 or 5: wherein R ₁ and R _{7 are} selected from CO ₂ X or PhCO ₂ X with X = 4-iodophenyl; 4-bromophenyl or 4-chlorophenyl; 4-vinylphenyl or 4-allylphenyl; or R ₁ and R 7 are selected from CO ₂ Y or PhCO ₂ Y with Y = 2-methyl-3-pentyne-2-yl or 3-tert-butyl-4,4-dimethyl-1-pentyn-3-yl, or R _{7 is} selected from CO ₂ Z, PhCO ₂ Z, C (O) NZ ₂ or PhC (O) NZ ₂ with (Z = alkyl, perfluoroalkyl, vinyl, allyl, homoallyl, aryl); where R ₂ , R ₃ , R ₄ , and / or R _{5 are} independently selected from H, F, an alkyl or an aryl; and wherein R _{6 is} selected from an alkyl and an aryl.
