Control of electron transfer in a conjugated porphyrin dimer by selective excitation of planar and perpendicular conformers.

Control of electron transfer in a conjugated porphyrin dimer by selective excitation of planar and perpendicular conformers.

A donor-acceptor system is presented in which the electron-transfer rates can be sensitively controlled by means of excitation wavelength and temperature. The electron donor is a butadiyne-linked zinc porphyrin dimer that is connected to a C(60) electron acceptor. The broad distribution of conformat...
