Abstract

Three novel Co-based coordination polymers including {[Co(L)(μ <subscript>3</subscript> -O) <subscript>1/3</subscript> ] <subscript>2</subscript> } <subscript>n</subscript> (1), {[Co(L)(bimb)]} <subscript>n</subscript> (2) and {[Co(L)(bimmb) <subscript>1/2</subscript> ]} <subscript>n</subscript> (3) (H <subscript>2</subscript> L = 2,6-di(4-carboxylphenyl)-4-(4-(triazol-1-ylphenyl))pyridine), bimb = 1,4-bis(lmidazol) butane, bimmb = 1,4-bis(imidazole-1-ylmethyl)benzene) were successfully prepared under solvothermal conditions and characterized. Single-crystal X-ray diffraction analyses revealed that 1 possesses a 3D architecture composed of a trinuclear cluster [Co <subscript>3</subscript> N <subscript>3</subscript> (CO <subscript>2</subscript> ) <subscript>6</subscript> (μ <subscript>3</subscript> -O)], 2 exhibits a 2D new topological framework with the point symbol (8 <superscript>4</superscript> ·12 <superscript>2</superscript> )(8) <subscript>2</subscript> , whereas 3 shows a unique six-fold interpenetrated 3D framework with a (6 <superscript>3</superscript> ·8 <superscript>2</superscript> ·10) <subscript>2</subscript> (6 <superscript>3</superscript> ) <subscript>2</subscript> (8) topology. Impressively, all of them can function as a highly selective and sensitive fluorescent sensor for the biomarker methylmalonic acid (MMA) via fluorescence quenching. The low detection limit, reusability and high anti-interference performance together make 1-3 become promising sensors for the practical detection of MMA. Furthermore, the successful application of MMA detection in urine sample was demonstrated, which may be a potential candidate for the further development of clinical diagnostic tools.<br />Competing Interests: Declaration of competing interest There is no competing interest declare.<br /> (Copyright © 2023 Elsevier B.V.
