CATALYSTS AND CYCLOPROPANATION OF PORPHYRINS(Abstracts)

摘要

Porphyrins show applications in different areas, with a special emphasis in medicine, namely in cancer photodynamic therapy . Requirements for a good photosensitizer include the light absorption features in the far-red region of the visible spectrum which is essential to achieve a therapeutic effect as deep as possible. In this way, a great effort has been put on the development and improvement of new methods to convert porphyrins into dihydroporphyrins and tetrahydroporphyrins.
