Abstract

Abstract : Fluorescent coordination polymers have drawn extensive attention in sensing applications. Herein, we report a carbazole‐based one‐dimensional coordination polymer [CdL(H2 O)(DMF)2 ]·DMF (CdL, H2 L = 9H‐carbazole‐2, 7‐dicarboxylic acid, DMF = N, N ‐dimethylformamide). In CdL, each Cd 2+ ion is four‐bridged by carboxylates, which is further linked by the carbazole units to form a one‐dimensional Cd–O–C chains along the c ‐axis. CdL displays high water stability in the pH range of 3–10. Luminescence experiments indicate that CdL could selectively detect Fe 3+ during the concentration range of 0–0.1 mm in water with a K sv of 8022 m −1 and picric acid (PA) within the concentration range of 0–0.05 mm in methanol solution with a K sv of 17948 m −1 respectively. The above results reveal that CdL can be applied as a multiresponse luminescence sensor for selectively sensing for Fe 3+ in water and PA in methanol solution.
