A water stable zirconium-diimide based metallogel (Zr@MG) with fibrous columnar morphology was synthesized and demonstrated selective detection of Cr2O72- and 2,4,6-trinitrophenol (TNP) in water. The Zr@MG gel also showed selective capture of positively charged methylene blue (MB) dye and effective iodine sequestration from vapor phase.
Sensing and monitoring hazardous contaminants in water and radioactive iodine sequestration is pivotal due to their detrimental impact on biological ecosystems. In this context, herein, a water stable zirconium-diimide based metallogel (Zr@MG) with fibrous columnar morphology is accomplished through the heat set method. The presence of diimide linkage with long aromatic chain manifests active luminescence properties in the linker as well as in the supramolecular framework structure. The as -synthesized Zr@MG xerogel can selectively detect Cr2O72-(LOD = 0.52 ppm) and 2,4,6-trinitrophenol (TNP) (LOD = 80.2 ppb) in the aqueous medium. The Zr@MG paper strip-based detection for Cr2O72-and nitro explosive makes this metallogel reliable and an attractive luminescent sensor for practical use. Moreover, a column-based dye separation experiment was performed to show selective capture of positively charged methylene blue (MB) dye with 98 % separation efficiency from the mixture of two dyes. Also, the Zr@MG xerogel showed effective iodine sequestration from the vapor phase (232 wt%).(c) 2022 Elsevier Inc. All rights reserved.
