A novel pillared-layer Cd-MOF was synthesized as luminescent sensor for detection of nitroaromatic explosives with highly selective and recyclable properties. The study also shows that the photoinduced electron transfer and resonance energy transfer were possible mechanisms of fluorescence quenching.

The kinetics of the polymerization of acrylonitrile and methacrylic acid photosensitized by cerous ions have been studied. Cerous salts have been photolyzed in different media by means of the flash technique and ceric ions were produced, accompanied by fluorescence. Quenching of the fluorescence of the excited ceric species has been investigated with and without the presence of monomer and it has been demonstrated that hydrogen ions are necessary for the polymerization reaction to proceed. The results are consistent with the following electron transfer processes: Ce 3+ . HOH + hv ^+ (Ce 4+ . HOH - )*, Ce 4+ . HOH - )* hv ^+ Ce 3+ . HOH+ hv ", Ce 4+ . HOH - )* +H + ->Ce 4+ . H 2 O+H', Ce 4+ . HOH - )* +H + + M ->Ce 4+ +H 2 M H', where M = monomer.

Disodium 1,5- and 1,8-anthracenedisulphonate (ADS) and 9-acetylanthracene form coloured CT complexes with methylviologen (MV2+) in aqueous and micellar media. The complex formation constants and molar absorptivities were determined by the Benesi-Hildebrandt method. In the fluorescence quenching, its static component plays the major role. The dynamic quenching component is determined by the rate constant of electron transfer from the S1 state of ADS to MV2+.
