Abstract

A D-A₁-A₂ type covalent triazine framework (CTF) was prepared for the photocatalytic hydrogen evolution (HER). In the resulting CTF-CZ-Bpy²⁺, 9-ethyl-9H-carbazole (CZ) group is used as the donor, triazine ring as the first acceptor, and cyclic diquat (Bpy²⁺) moiety as the second acceptor. Both experimental and theoretical results show that the D-A₁-A₂ structure significantly enhances the efficiency of photogenerated charge separation and transfer. As a result, CTF-CZ-Bpy²⁺ demonstrated outstanding photocatalytic HER activity with a yield rate of 31.1 mmol g⁻¹ h⁻¹, which is 7.8 times higher than that of nonfunctionalized CTF-CZ-Bpy.

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
