ABSTRACT=<p>Two-dimensional (2D) metal-organic frameworks (MOFs) have been extensively investigated as oxygen evolution reaction (OER) materials because of their numerous advantages such as large specific surface areas, ultrathin thicknesses, well-defined active metal centers, and adjustable pore structures. Five Co-metal-organic frameworks, namely, [Co(L) (4.4′-bbidpe)H<sub>2</sub>O]<sub>n</sub> [YMUN 1 (YMUN for Youjiang Medical University for Nationalities)], {[Co<sub>2</sub>(L)<sub>2</sub> (4.4′-bbibp)<sub>2</sub>]·[Co<sup>3</sup>(L) (4.4′-bbibp)]·DMAC}<sub>n</sub> (YMUN 2), [Co(L) (3,5-bip)]<sub>n</sub> (YMUN 3), [Co(L) (1,4-bimb)]<sub>n</sub> (YMUN 4), and [Co(L) (4.4′-bidpe)H<sub>2</sub>O]<sub>n</sub> (YMUN 5), were designed and fabricated from flexible dicarboxylic acid 1,3-bis(4′-carboxylphenoxy)benzene (H<sub>2</sub>L) and rigid/flexible imidazole ligands. Their frameworks consist of two-dimensional lamellar networks with a number of differences in their details. Their frameworks are discussed and compared, and their oxygen evolution reaction electrochemical activities and photocatalysis dye degradation properties are investigated.</p>
