摘要：

Different metal tetrasulfophthalocyanines and rose bengal were employed as photosensitizers in the photooxidation of phenol, cyclopentadiene and (S)-(-)-citronellol. Ionically polymer bound photosensitizers were easily obtained by the reaction of negatively charged low-molecular-weight phthalocyanines with the strong basic anion exchanger Amberlite(R) IRA 400. The activities of the low-molecular-weight and the polymer systems are compared. Especially immobilized phthalocyanines which exhibit the advantages of good activity, as well as stability against photobleaching, and can be used repeatedly.
