The photophysical and electrochemical properties of a dyad comprising an expanded acridinium light-harvester, coupled via a triple bond to a trialkyloxybenzene donor, are described. Laser excitation of the dyad in 1,2-dichloroethane (DCE) results in rapid charge shift (5 ps) followed by slower charg...

| description | The photophysical and electrochemical properties of a dyad comprising an expanded acridinium light-harvester, coupled
via
a triple bond to a trialkyloxybenzene donor, are described. Laser excitation of the dyad in 1,2-dichloroethane (DCE) results in rapid charge shift (5 ps) followed by slower charge recombination (81 ps) to completely restore the ground state. Discrimination between forward and return electron transfer (

Laser excitation of the dyad results in rapid charge shift and is followed by slower charge recombination to restore the ground state. |
