We have seen so far that especially the ends of the series, namely CTF-02-Bpy and CTF-02 possess features that should boost their performance in photocatalysis. On the one side, CTF-02-Bpy shows improved light absorption in the visible region and efficient charge generation, but very low thermodynamic driving force for TEOA oxidation. On the other hand, CTF-02 possesses high thermodynamic driving forces and good visible light induced charge separation and transport, but the highest hydrophobicity. We thus suppose that by the rational design and precise control of the material properties, we should find the material with optimum composition and thus properties, resulting in a maximum in performance of the catalysts in photocatalytic HER.
