“…Therefore, it has notably raised the knowledge level about MOFs [220]. Metal-Organic Frameworks (MOFs) are another class of 3D nano-adsorbents that allow for adsorption of organic dyes as well as their photodecomposition [217,218]. Such porous crystalline inorganic-organic hybrid materials offer desirable host-guest chemistry and also widely enable tuning of their porosity with respect to shape, functionality, and size.…”

Clean water is a vital element for survival of any living creature and, thus, crucially important to achieve largely and economically for any nation worldwide. However, the astonishingly fast trend of industrialization and population growth and the arisen extensive water pollutions have challenged access to clean water across the world. In this regard, 1.6 million tons of dyes are annually consumed. Thereof, 10%–15% are wasted during use. To decolorize water streams, there is an urgent need for the advanced remediation approaches involving utilization of novel materials and technologies, which are cost and energy efficient. Nanomaterials, with their outstanding physicochemical properties, can potentially resolve the challenge of need to water treatment in a less energy demanding manner. In this review, a variety of the most recent (from 2015 onwards) opportunities arisen from nanomaterials in different dimensionalities, performances, and compositions for water decolorization is introduced and discussed. The state-of-the-art research studies are presented in a classified manner, particularly based on structural dimensionality, to better illustrate the current status of adsorption-based water decolorization using nanomaterials. Considering the introduction of many newly developed nano-adsorbents and their classification based on the dimensionality factor, which has never been employed for this sake in the related literature, a comprehensive review will be presented.

“…This situation was not the case for Rhodamine 6G (R6G + ) and Butyl Rhodamine B (BRB + ) with a size exceeding the pore size of the MOF. Regarding adsorption-based removal of organic dyes by MOFs, an interested reader can refer to a number of relevant, useful reviews [217,[226][227][228].…”

“…This is undoubtedly related to their chemical flexibility and the wide range of organic substrates that can yield oxamate ligands. Considerable work has been devoted so far to phenyl‐based oxamate ligands, and more recently, amino acid‐based oxamate ligands have also shown strong appeal . In the case of phenyl derivatives, the role of alkyl substituents and their steric hindrance has also been probed to investigate the effect on the magnetic interactions and on the dimensionality of the compounds .…”

The reaction of the N‐(2‐hydroxyphenyl)oxamate ligand (ohpma) has been investigated with cobalt(II) and copper(II) ions. It has led to two coordination compounds, (TMA)3[{CoIII(ohpma)2CoII(MeOH)2}3]·10H2O·5MeOH (1) and (HNEt3)[Cu(ohpma)] (2). Both compounds have been characterized by single‐crystal X‐ray diffraction and magnetometry. The X‐ray diffraction studies have revealed atypical structures that are not commonly observed in oxamate coordination chemistry with a macrocyclic arrangement for the mixed‐valence cobalt‐based complex 1, and a helical chiral chain for compound 2. In the latter, the bis‐polydentate nature of the (ohpma)3– ligand with distinct tridentate and bidentate coordination sites creates a chirogenic center on the copper ion. The investigation of the magnetic properties shows for complex 1 a single‐molecule magnet behavior detectable under static field, while antiferromagnetic interactions dominate the behavior of 2.

“…[15,20] In this context, removal of toxic dyes by adsorption on suitable sorbent is compelling as it eliminates the possibility of formation of toxic side products. [21][22][23][24] The existing literature reports the sorbents that are capable of removing dyes only either at low pH, or at low or higher temperature. [25][26][27] Often the sorbent synthesis requires very high temperature.…”

We report the design and synthesis of thiol-norbornene based ingenious gels with pendent quaternary ammonium substituents on the norbornene backbone that are conducive to remove toxic anionic azo dye acid orange 7 (AO7) from wastewater. Three different alkyl side chains on the dangling quaternary ammonium moiety were chosen prudently and their performance towards removal of azo dye was scrutinised. The characterisation of all the precursor monomers and the ensuing gels were accomplished by 1 H, 13 C NMR and Mass spectrometry. The influence of extent of crosslinking on the solvent uptake ability was investigated and the swelling nature of the gels were correlated with the solubility parameter of different solvents. The surface morphology of the gels as visualised by FE-SEM analysis, revealed macropores in the range 4-12 μm. The relationship between the composition of quaternary ammonium moiety on the gels and their viscoelastic properties was realised. The dye removal kinetics as observed from UV-Vis spectra were best correlated with the pseudo-second-order model and the adsorption isotherm of dye removal process was best fitted with the Langmuir isotherm model with high correlation coefficient. The material was found to be fairly recyclable up to 10 th cycles with loss of only 8% efficiency. To the best of our knowledge, this is the first ever report on the removal of anionic dye based on thiolnorbornene photo crosslinked network. We believe that this design and composition-property relationship will enthuse the researchers to develop efficient chemical adsorbents based on environmentally benign systems.
