Abstract:
Novel water-soluble polymeric photosensitizers based on the natural polymer chitosan were synthesized and studied. The modified chitosans contain covalently attached Rose Bengal. The polymers absorb light from the visible spectral region and generate singlet oxygen. They can serve as environmentally friendly, biodegradable polymeric photosensitizers, which can use light from a visible spectral region to initiate photooxidation of organic compounds in water.
