Remarkable Dependence of the Final Charge Separation Efficiency on the Donor-Acceptor Interaction in Photoinduced Electron Transfer
The unprecedented dependence of final charge separation efficiency as a function of donor–acceptor interaction in covalently‐linked molecules with a rectilinear rigid oligo‐p‐xylene bridge has been observed.

Zusammenfassung: | The unprecedented dependence of final charge separation efficiency as a function of donor–acceptor interaction in covalently‐linked molecules with a rectilinear rigid oligo‐p‐xylene bridge has been observed. Optimization of the donor–acceptor electronic coupling remarkably inhibits the undesirable rapid decay of the singlet charge‐separated state to the ground state, yielding the final long‐lived, triplet charge‐separated state with circa 100 % efficiency. This finding is extremely useful for the rational design of artificial photosynthesis and organic photovoltaic cells toward efficient solar energy conversion.

This finding is relevant to the rational design of artificial photosynthesis and organic photovoltaic cells. |
