A Type of Conjugated Fuse Heterocyclic Schiff Base Colorimetric andFluorescent Chemosensors for Selective Detection of Picric acid (PA)
Abstrak
: A series of Schiff base chemosensors (M1, M2 and M3) were designed and synthesized based on conjugated fuse heterocyclic aldehyde thiosemicarbazone. Optical properties of fluorescent probes M1, M2, and M3 toward various nitro explosives 2,4-dinitrotoluene (DNT), o-nitrophenol (ONP), p-nitrophenol (PNP), phenol (PhOH) and nitromethane (NM) were investigated, M1, M2, and M3 could selectively recognize PA with an obvious color change and fluorescence quenching, even in the presence of other coexistence nitro explosives. The detection limit of M1, M2, and M3 were 1.18and#215;10-7 M, 1.13and#215;10-7 M, 1.09and#215;10-7 M, respectively.
