Chemosensor of imidazole derivative (4-(4,5-diphenyl-1H-imidazol-2-yl)-2-methoxy-6-nitrophenol) (IMD-1) has been synthesized and tested for amines sensor. IMD-1 was synthesized from the reaction of 5-nitrovanillin, 1,2-diphenylethane-1,2-dione (benzil), and ammonium acetate using reflux method. IMD-1 showed fast respond and color change from light orange to orange in naked eye compared with the imidazole derivative without nitro group (IMD-0). The IMD-1 could detect butylamine quantitatively with detection limit of 1.03 x 10-4 M.

Rhodamine B thiohydrazide (RBS) was firstly employed as turn-on fluorescent probe for hypochlorite in aqueous solution and living cells. It exhibits a stable response to hypochlorite from 1.0×10-6to 1.0×10-5M with a detection limit of 3.3×10-7M. The response of this probe to hypochlorite is fast and highly selective compared with other reactive oxygen species (such as.OH,1O2, H2O2) and other common anions (such as X-, ClO2-, ClO4-, NO3-, NO2-, OH-, Ac-, CO32-, SO42-).
