The role of π‐conjugated molecular bridges in through‐space and through‐bond electron transfer is studied by comparing two porphyrin–fullerene donor–acceptor (D–A) dyads. One dyad, ZnP–Ph–C60 (ZnP=zinc porphyrin), incorporates a phenyl bridge between D and A and behaves very similarly to analogous dyads studied previously. The second dyad, ZnP–EDOTV–C60, introduces an additional 3,4‐ethylenedioxythienylvinylene...
A series of pyrazolino[60]fullerenes has been prepared in one pot by 1,3-dipolar cycloaddition to C 60 of the corresponding nitrile imine, which was generated in situ from the corresponding hydrazone. A range of donors and acceptors were introduced as substituents. Electrochemical and photophysical studies have revealed weak ground-state interactions between the organic addends and the...
