ABSTRACT Three novel Cd (II) coordination polymers (Cd‐CPs) ( 1–3) , with the formula of [Cd(2‐DBB)(1,4‐bibz)(OH)]·H 2 O( 1 ), [Cd 3 (3‐DBB)(1,4‐bibz) ]·2H and [Cd(4‐HDBB)(1,4‐bibz) 0.5 ]( ) based on three soft organic isomers: n ‐(3,5‐dicarboxylato benzyloxy) benzoic acid = 2, 3, or 4‐H DBB), one linear N‐donor ligand 1,4‐bis(1‐imidazoly) benzene (1,4‐bibz) have been synthesized hydrothermally characterized by X‐ray single crystal diffraction, elemental analyses, thermogravimetric, UV, IR, PXRD technologies. The significant structural differences are both featuring 2D networks, but 3D framework due to change H DBB isomers. Despite differences, series Cd‐CPs exhibits similar fluorescence sensing properties for nitrobenzene (NB) low detection limits 1.05 μM 44.3 nM 59.1 respectively. However, these discovered detect different antibiotics, respectively: had a quenching effect ornidazole (ONZ) chloramphenicol (CHI). results theoretical calculation verified mechanism Cd‐CPs. Therefore, might be potential luminescent materials antibiotics NB in future.
