Four novel coordination polymers (CPs) assembled with [2,2′‐bifuran]‐5,5′‐dicarboxylic acid (H 2 L ) and metal ions Zn II , Cd II or Co II have been successfully synthesized. Their molecular structures have been determined to be Zn( L )(H 2 O) 2 (1), [Zn( L )(DMF)] 2 (2), [Cd( L )(EtOH)(DMF) 2 ] 2 (3) and Co( L )(H 2 O) 4 ·(H 2 O) 2 (4) by crystallographic analysis. It is found that (2) exhibits a two‐dimensional infinite framework, whereas the others exhibit a one‐dimensional framework. Both (2) and (3) exhibit ligand‐based emission which is blue‐shifted compared with the emission from the H 2 L ligand. Time‐resolved spectroscopic measurement reveals that the complexes exhibit a similar lifetime with that of the ligand, which confirms that the emission of the complexes originates from the ligand.
