摘要：
Rose Bengal (4,5,6,7-tetrachloro-2',4',5',7'-tetraiodofluorescein, RB), a xanthene dye well-known as singlet molecular oxygen photosensitizer, was bound to the polymeric matrix poly(butadiene-hydroxyethylmethacrylate-epichlorhydrin) (PB-HEMA-ECH). The new polymer-bound dye (P-RB) was investigated as sensitizer for the photooxidation in air equilibrated solutions of model compounds (Q). Comparative results of degradation of these compounds suggest the generation of singlet oxygen. Also P-RB showed good stability and was reused.
