Selective Detection of nano-molar range Noxious Anions in Water by a Luminescent Metal-Organic Framework

A new metal-organic framework (MOF) showed excellent recognition ability towards five toxic oxo-anions viz. arsenate (HAsO42-), phosphate (PO43-), permanganate (MnO4-), chromate (CrO42-) and dichromate (Cr2O72-) in aqueous medium upon irradiation...

Rapid, selective capture of toxic oxo-anions of Se(iv), Se(vi) and As(v) from water by an ionic metal–organic framework (iMOF)

Fast, selective capture of oxoanions of selenium [Se(iv), Se(vi)] and arsenic [As(v)] by a chemically stable cationic MOF, viz. iMOF-3C, is reported. The compound successfully yields drinking quality water from complicated matrix including river water.

A Luminescent Cationic MOF for Bimodal Recognition of Chromium and Arsenic based Oxo-anions in Water

Water pollution because of heavy metals and their toxic oxo-anionic derivatives such as CrO42−, Cr2O72-, HAsO42-, HAsO32- has become one of the most critical environmental issue. To address this, herein...

Revisiting salicylidene-based anion receptors

Salicylidene Schiff bases undergo imine bond hydrolysis in the presence of halides and oxo-anions in aprotic media, raising fundamental questions on the applicability of salicylidene-based receptors as anion sensors.

Coordination networks for the recognition of oxo-anions

Utilization of luminescent crystalline coordination networks (LCPs/LMOFs) for the recognition of various oxo-anions in aqueous environment has received significant interest in the context of environmental remediation.
