• A series of 2D isomorphous MOFs [M (HBTC)(BMIOPE)·DMF·H2O]n (M = Zn (1), Zn0.7Co0.3 (2), Zn0.5Co0.5 (3), Zn0.3Co0.7 (4), Co (5), H3BTC = 1,3,5‐benzenetricarboxylic acid, BMIOPE = 4,4′‐bis(2‐methylimidazol‐1‐yl)diphenyl ether) were synthesized to investigate the correction between the center metal ions and the photocatalytic behaviors. The photocatalytic results show that with the increase of Co2+ content, the photodegradation properties are continuously improved from 1 to 5, which fully indicate that only changing metal ions could regulate the photodegradation properties. In detail, 1 is an inactive photocatalyst to degrade methylene blue (MB), while 5 exhibits preeminent photocatalytic properties under visible light irradiation. Moreover, 1 shows good selective sensing toward Fe3+, Cr3+, UO22+, CrO42− and Cr2O72− ions in aqueous solution. To the best of our knowledge, 1 is the first MOF example for the optical detection of Fe3+, Cr3+, UO22+, CrO42− and Cr2O72− ions in aqueous solution. Five isomorphous Co‐Zn MOFs [M (HBTC)(BMIOPE)·DMF·H2O]n (M = Zn (1), Zn0.7Co0.3 (2), Zn0.5Co0.5 (3), Zn0.3Co0.7 (4), Co (5), H3BTC = 1,3,5‐benzenetricarboxylic acid, BMIOPE = 4,4′‐bis(2‐methylimidazol‐1‐yl)diphenyl ether) have been synthesized, showing the photodegradation modulate by the Co2+ content. Meanwhile, 1 shows good selective sensing toward Fe3+, Cr3+, UO22+, CrO42− and Cr2O72− ions in aqueous solution.
