Photocatalytic Activities

Photoexcited perylene diimide radical anions exhibit remarkable substituent-dependent photocatalytic activities towards the reduction of aryl halides, which are mainly controlled by their excited-state reduction potentials and SOMO−1 energies.

Extending the acetylide ligand π-conjugation diminishes the terminal substituent effect on the lowest excited states, but expands the triplet excited-state absorption to the near-IR region.

First Excited State

Anodic and cathodic half wave potentials of porphin, tetraazaporphin, Mg (II)-tetraazaporphin, uroporphyrin I and phtalocyanin were measured respectively calculated, and also the reduction potentials of pheophytin a and thioazacarbocyanines. These and the redox potentials of further porphins were compared with some of their photochemical reaction. It was found that the energy difference between the first excited state and ionization in photochemical active porphins are smaller than in less active dyes. An electron from the first excited state of chlorophyll a e. g. is 0,95 eV more easy removed than from phtalocyanin.The influence of metal ions in systems with Η-bonding, e. g. porphins, 8-oxychinolin and proteins will be discussed.
