New Approach

According to the principle of dynamic quenching a new ON-OFF fluorescent chemosensor for Cu2+ions was designed, this chemosensor was composed of p-tert-butylthiacalix [arene (TCA),sodium dodecyl sulfate (SDS) and perylene through the form of self-assembly in aqueous solution. Addition of Cu2+ions could result in a quenching of the fluorescence emission of perylene inside micelles, which due to intramicellar complex-fluorophore electron-transfer or energy-transfer effects induced by the complexation of TCA with the Cu2+ions.The experimental results indicated that: Under the condition of TCA/perylene was 800/1, SDS concentration was 150mmol/L and pH value above 9, according to the fluorescence quenching ,within a certain range of the concentration of Cu2+ion can be linearly determined.

Selective Interactions

Herein, we report the synthesis of two amphiphilic porphyrins having pyridinium moieties and their anion recognition properties in aqueous medium. The study of their interactions with various anions reveals that these porphyrins exhibit unique and selective interactions with CN- ions when compared to the other anions. The addition of CN- ions to an aqueous solution of the butyl porphyrin resulted in a hypochromicity of ca. 78% at 419 nm with a concomitant band formation at 449 nm in the absorption spectrum. Similarly, we observed ca. 82% quenching in the emission intensity by the addition of 12.5 M of CN- ions in the fluorescence spectrum of the porphyrin mediated through aggregation. The limit of detection of CN- ions was found to be ca. 49 ppb and the nature of interactions has been studied through various microscopic and spectroscopic techniques. These studies have confirmed 1,4-addition of CN- ions to the pyridinium moiety of the porphyrin system, which led to the aggregation induced self-assembly resulting in the sensitive detection of CN- ions through changes in absorbance and fluorescence intensity in aqueous medium.
