Intramolecular rotation in a porphyrin dimer controls singlet oxygen production.

Abstract:

The efficiency with which a conjugated porphyrin dimer photosensitizes singlet oxygen production is shown to depend on the excitation wavelength, particularly in a viscous medium. This unprecedented behavior reflects viscosity-dependent dynamics that serve to interconvert two excited singlet state conformations of the porphyrin dimer. The efficiency of intersystem crossing from the two singlet state conformations to a common triplet state is shown to be different. In a viscous medium, each ex...
