Method and sensor for detection of triacetone triperoxide (tatp), diacetone diperoxide (dadp), hexamethylene triperoxide diamine (hmtd) and hydrogen peroxide

A sensor comprising a substrate and a first mixed layer arranged on the substrate, the first mixed layer comprising:

• a molecular probe;
• a sulfonic acid;
• and
• a hydrophilic compound;
• wherein the molecular probe is selected from:
• a triarylamine;
• a biphenyl diamine, a benzene diamine, a diaryl benzamide, and/or a triarylborane.

A method of fabricating a sensor comprising:

• mixing a molecular probe, a sulfonic acid, and a hydrophilic compound;
• and
• forming a first mixed layer comprising the mixed molecular probe, the sulfonic acid, and the hydrophilic compound on a substrate;
• wherein the molecular probe is selected from:
• a triarylamine;
• a biphenyl diamine, a benzene diamine, a diaryl benzamide, and/or a triarylborane.

A molecular probe for detecting an analyte selected from triacetone triperoxide, diacetone diperoxide, hexamethylene triperoxide diamine, and hydrogen peroxide by means of a fluorescence signal generated in response to an excitation in the wavelength range between 330-390 nm,

• wherein the molecular probe is a triaryl borane dye according to formula (14*):
• wherein
• R52=B(O)22−, B(OH)(O)−, B(OH)2, B(OH)3, B(OMe)2, B(OEt)2, B(OPr)2, B(Oalkyl)2, B(OPh)2, B(Oaryl)2, or B(OCH2CH2)nOR2)2, wherein R2=H, Me, or alkyl with x=1, 2, 3;
• or
• R52=boronic ester respectively cyclic boron compounds of glycol, pinacol, 1,4-butanediol, 1,5-pentanediol, tartaric acid, 2,2-dimethyl-1,3-propanediol, a cyclic boronate of methyliminodiacetic acid (MIDA) i.e. at least one of the cyclic boronates of MIDA, a cyclic boronamide of brenzcatechine, 1,8-diaminonaphthalene, o-phenylenediamine, or derivatives thereof.
