The electronic structure of metal complexes plays key roles in determining their catalytic features. However, controlling structures to regulate reaction mechanisms is fundamental interest but has been rarely presented. Herein, we report tuning Cu porphyrins switch pathways the hydrogen evolution (HER). Through controllable and regioselective β-oxidation porphyrin 1, synthesized analogues 2-4 with one or two β-lactone groups either a cis trans configuration. Complexes 1-4 have same Cu-N

Electrocatalytic hydrogen generation in alkaline medium has become widely used a variety of sectors. However, the possibility for additional performance improvement is hampered by slow kinetics. Because this restriction, careful control over processes such as water dissociation, hydroxyl desorption and recombination required. Covalent organic frameworks (COFs) based on porphyrin polyoxometalates (POMs) show encouraging electrocatalytic performance, offering viable route effective sustainable generation. Their specific architectures lead to increased activity, which makes them excellent choices developing electrolysis clean energy conversion method medium. In regard, TTris@ZnPor Lindqvist POM were coordinated create new eco-friendly highly active covalent framework (TP@VL-COF). order describe TP@VL-COF, extensive structural morphological investigations carried out through FTIR,
