Abstract
Methods, compositions, and systems for detecting explosives is disclosed and described. A sensor for detecting explosives can comprise a porous hydrophilic material modified with a series of π conjugated molecules with the general structure: [EW]-[CS]-[PED] wherein EW is an electron withdrawing group, CS is a conjugated system, and where PED is a pre-electron donating group. The porous hydrophilic material is capable of detecting hydrogen peroxide by reacting the aryl boronate group (or other Pre-ED groups) with the hydrogen peroxide to provide a fluorescent change.
