“…It should be noted that the lately reported Zr-DMTDC material was prepared under solvothermal conditions (220°C for 16 h) in DMF by using conc. HCl as an additive with a ZrCl 4 /HCl molar ratio of 1:2 [38]. However, systematic investigation of the influence of ZrCl 4 /HCl molar ratio on the crystallinity of the compound was not carried out.…”

“…Herein, we wish to report on the modulated synthesis, thorough characterization, thermal and chemical stability as well as gas sorption and transition-metal cation separation properties of compound 1. During the preparation of the manuscript, the stability and mercury vapor sorption behavior of this MOF have been reported [38]. However, the synthesis and activation routes of our compound are different.…”

“…They have been used during the solvothermal synthesis of many Zr(IV) based MOF materials having UiO-66 structural topology in order to enhance their crystallinity [15,16,23,33,38,. Typically, modulators include monocarboxylic acids (e.g.…”

“…MOFs containing thiol groups have exhibited prospective for effective mercury sorption [36] and grafting of Pd(II) ions [37] for Suzuki-Miyaura coupling reactions. The potential of thienothiophene based MOFs for mercury vapor sorption [38] as well as separation [39] of transition-metal ions has been documented. However, the number of reports describing the utilities of sulfur-tagged (especially thienothiophene based) MOFs is still relatively less.…”

“…However, as a greater understanding is reached on the water stability of MOFs, a new breed of water-stable MOFs is being developed. These materials can withstand immersion in water for extended periods of time, in large pH ranges (0 to 12) (33). Overall, MOFs can appear as promising candidates for the treatment of waste water streams owing to their high porosities and specific adsorbate/adsorbent interactions.…”

Towards the use of metal–organic frameworks for water reuse: a review of the recent advances in the field of organic pollutants removal and degradation and the next steps in the field

Water reuse is becoming increasingly important as more and more areas in the world are facing water stress issues. Treatment of wastewater to attain the purity required for various usages from culture irrigation to drinking water is therefore key. Several water treatment options are already in place and while we will continue to use them, parallel efforts are required to: (i) address the removal of the most persistent chemicals in water and (ii) provide solutions for local communities. Recently, several studies on the use of metal-organic frameworks (MOFs) for the adsorption and photocatalytic degradation of organics in water have been reported. This enthusiasm originates from the large porosity and chemical tunability of MOFs -beneficial for adsorption -as well as their catalytic nature -beneficial for degradation. The present reviews proposes a comprehensive and critical analysis of the most recent studies on the use of MOFs for organics adsorption and photocatalytic degradation. The potential to use MOFs to catalyze the production of H2 from organic molecules, like water contaminants, is also addressed. Overall, the discussion is organised based on the type of organic pollutants targeted and encompasses those released in industrial, domestic and agricultural wastewater streams.3

An ew Hf IV -basedm etal-organic framework with UiO-66 topology was synthesized via ao ne-step solvothermal methodb yu sing 3-methyl-4-phenylthieno[2,3-b]thiophene-2,5-dicarboxylic acid (H 2 MPTDC) as al igand.T he MOF material showedahigh stability in ab road pH range (from pH 2t op H12) in an aqueous medium. The presenceo fh ydrophobic methyl and phenyls ubstituents in the carboxylic acid ligand and strong HfÀOb ondp lay crucial roles in its stability.T he new MOF material was systematically characterized by various techniques such as XRPD,N 2 sorption, thermogravimetric analyses and FT-IR spectroscopy.T he photophysical properties of the MOF material were also examined by steady-state and time-resolved fluorescence studies. It was observed that the blue fluorescenceo ft he MOF material was selectively quenchedi nt he presence of Fe 3 + ion in pure aqueous medium. Am echanistic study disclosed that quenching occursv ia as trong inner filter effect (IFE) arising from Fe 3 + ion in aqueous medium. Interestingly,t he fluorescence of the MOF material can be recovered by elimination of the IFE of Fe 3 + ion via reduction of Fe 3 + ion by ascorbic acid (AA). Based on the fluorescencer ecovery by AA, aM OF based on-off-on probe was developed for the sensing of Fe 3 + ion and AA in aqueous medium. Inspired by this reversible sensing event, we demonstrate basic (NOT,O R, YES, IN-HIBIT and IMP) and higher integrated logic operations utilizing this fluorescent MOF.T his MOF-based logic systems could be potentially used for next-generation logic-gate based analytical applicationsa sw ell as for the detection and discrimination of targeted molecules in various complex domains.
