Si. Vandijk et al., 2-STEP PHOTOINDUCED CHARGE SEPARATION AND UNEXPECTEDLY FAST ONE-STEP CHARGE RECOMBINATION IN A LINKED DONOR(2) DONOR(1) ACCEPTOR SYSTEM, Chemical physics letters, 214(5), 1993, pp. 502-506
Photoinduced sequential two-step electron transfer occurs upon excitat
ion of the 1,3-diphenylpropanedioato boron oxalate electron acceptor i
n a novel trichromophoric donor2-donor1-acceptor (D2-D1-A) system. The
D2-D1+-A- state is fluorescent, while the D2+-D1-A- state is observed
by transient absorption. The final giant dipole state, which is forme
d in almost-equal-to 90% yield, is remarkably short-lived.
