A new polymeric photosensitizer, hydrophobically-modified dextran (DEX-ICN), was synthesized and studied. The hydroxyl groups in dextran have been substituted using 1-naphthyl isocyanate. The modified dextran was characterised by IR, UV - Vis and fluorescence spectroscopies , and by GPC chromatography. Photophysical and photochemical properties of DEX-ICN were investigated. The polymer was found as being able to solubilize hydrophobic compounds such as perylene. The DEX-ICN was then tested as the photosensitizer for photodegradation of pesticide paraoxon-ethyl (POE). The effective quenching of DEX-ICN fluorescence by POE and the rate of photosensitized degradation of POE by the polymer proved that hydrophobically-modified dextran can be an efficient photosensitizer in the processes of photodegradation of environmental pollutants.
