Poly(p-(trifluorovinyl)benzophenone) and Poly(p-trifluorovinyl)acetophenone). Photostable Polymeric Triplet Energy Transfer Donors

Article abstract of DOI:10.1021/jo01302a030

The synthesis of UV-stable photosensitizers poly(p-(trifluorovinyl)benzophenone) and poly(p-(trifluorovinyl)acetophenone) and their use as a homogeneous and heterogeneous triplet-state energy-transfer donor are herein described.The photosensitizers are advantageous both because of the separation advantages provided by the macromolecule and the nearly diffusion-controlled energy-transfer rate of a sensitizer in solution.Poly(p-trifluorovinyl)acetophenone) is insoluble in certain solvents, thus providing the separation advantages of a heterogeneous energy-transfer donor.
