Porphyrinoids are considered perfect candidates for the preparation of model electron donor-acceptor (D-A) systems as they
enable fast and efficient photoinduced electron transfer. Herein,
we report on the synthesis and photophysical characterization
of a ZnPc SubPc conjugate covalently connected through a
short-range alkyne spacer. We designed and prepared the
conjugate, which comprise, on the one hand, a perfluorinated
SubPc with strong electron acceptor character and, on the
other, a Pc peripherally functionalized with carbazoles with
strong electron donor character. Photoinduced electron transfer
events are in-depth analyzed by several techniques, including
steady-state absorption, time-resolved emission and transient
absorption measurements on different time scales. Our studies
confirm a full charge separation occurring from a photoexcited
charge transfer state
