A Novel Electron Donor‐Acceptor Carbazole‐Zn (II) Phthalocyanine – Perfluorinated Subphthalocyanine Conjugate: Synthesis, Characterization, and Photoinduced Electron‐Transfer
Abstract: 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.
