Abstract
Photoinduced electron transfer rates are reported for a pair of rigid bichromophoric molecules, 1(8) and 3(8), in a variety of solvents. It was found that intramolecular electron transfer in 1(8) is up to five times faster than in 3(8). X-ray crystallography revealed that the cyclopentyl ring attached to the dicyanoethylene group is “flatter” in 3(8) compared to 1(8), and this results in diminished through-bond coupling in 3(8) compared to 1(8). This conclusion is reinforced by the observation that the calculated through-bond π, π and π * interaction energies in dienes 7(6) and 9(6) are larger than those in the dienes 8(6) and 10(6), respectively.
