英文摘要 | Upon the addition of imidazole (Im) to the artificial photosynthetic systems composed by ZnTPP/BQ and p-H2TPP-NH-CO-CH2-BQ, half-lives of ESR signals of semibenzoquinone radical BQ(.-) and -CH2-BQ(.-) are significantly prolonged by the secondary electron transfer pathway from imidazole to porphyrin cation in polar solvents. The imidazole cation radicals (Im can simultaneously be identified by PBN(spin trap) both in BQ/ZnTPP/Im and p-H2TPP-NH-CO-CH2-BQ systems when laser-flashing. On the basis of our ESR observation, a secondary electron transfer mechanism can be proposed as follows: (1) TPP+hv-->TPP*; (2) TPP*+BQ-->TPP.++BQ(.-); (3) TPP.++Im-->TPP+Im(.+). |
