  • Based on both organic synthesis and theoretical calculations on the effects of molecular orbital energy levels of amines on the fluorescence properties of the fluorophore, fluorescent "turn-on" chemosensors detecting hazardous substances, including aldehyde chemicals and $Hg^{2+}$ ion, were developed.

  • We exploited a new molecular system - acetylcholine (neurotransmitter) detection system as a building block for the perfect molecular information system (sensing membrane of the chemical sensor) - using water soluble calix[n]arene-p-sulfonates which are useful even in aqueous (water/methanol) neutral solution. This achievement is due to several outstanding properties of these calix[n]arene derivatives such as low $pK_{a}$ values, cation-interactions, and high water-solubility, etc.

  • cis,cis-1,2,3,4-Tetraphenylbutadiene has been synthesized and its optical properties are investigated by using UV-Vis absorption and fluorescence spectroscopy. Thin films of tetraphenylbutadiene prepared from thin layer chromatography(TLC) displays strong luminescence and used for the detection of vapor of organic halide. Tetraphenylbutadiene shows dramatic quenching photoluminescence under exposure of chloroform vapor.
