As proposed by theoretical calculations, upon excitation of the Ru-CTF material a series of steps could generate a long-lived charge separated state that can be singlet or triplet in nature and where negative charge is localized at the CTF moiety and the positive one is located at the Ru center, [CTF •--Ru III ]. Since the ethyl units act as an electronically isolating unit, the back electron transfer needs to occur most likely through space. In addition, the negative charge in the triazine unit can be further delocalized over several triazine units, that do not have sufficiently close Ru centers to interact with, since the degree of functionalized pyridyl units in the CTF-Ru is only 14%. As a result of this electron density dilution effect and the very weak electronic coupling between the catalyst and the absorber, the back electron transfer is sufficiently slow so that it can compete with the SEA for the charge separated state even at the highest Ru oxidation state, leading to the generation of O2. This phenomenon highlights the synergistic effect of a localized charge at the Ru center of the molecular catalyst and the capacity of the 2D CTF polymeric structures to delocalize the negative charge over a large distance. This is reminiscent of the Zscheme in photosynthesis in green plants and algae, where the positive charge is localized at the OEC-PSII but the negative charge is spatially removed away via series of chained electron transfer steps involving initially pheophytin (Pheo) and then quinones Qa and Qb. Finally, the present work with the molecular hybrid material strategy represents a step forward towards efficient photocatalysts for water splitting with sacrificial less reagents, given the spatially controlled anchoring of oxidation and reduction catalysts that will avoid undesired reactions and that can be achieved via different anchoring strategies.
