Abstract
Iodine radioisotope, as one of the most important fission products of uranium, may cause severe damage to human health when it is accidentally discharged into the environment. Hence, efficient removal of radioactive iodine is one of the most critical issues for both used nuclear fuel (UNF) reprocessing and environmental remediation. In this work, three metal-organic gels (MOGs) were introduced for iodine removal. The presented zirconium-based MOGs, namely, CWNU, CWNU-NH2, and CWNU-2NH2, were prepared via moderate solvothermal reactions. These MOGs all exhibit excellent chemical stability and reusability, marked iodine sorption capability, and favorable machinability, which can even rival commercial ones. The sorption capacities are determined to be 3.36, 4.10, and 4.20 g/g, respectively. The increased amount of amino group is considered to be responsible for the elevated iodine sorption capacity and kinetics, as confirmed by combined sorption studies and XPS analysis. The presented work sheds light on the utilization of MOGs for radioiodine capture.

Abstract
The benzimidazole moiety, being a versatile heterocyclic unit, finds potential utility in
multiple applications ranging from material science to medicinal chemistry. Benzimidazole derivatives
are widely chosen as a multifunctional unit for the synthesis of bioactive organic compounds
because of their structural similarities to the natural nucleotides. They are also used as heteroaromatic
scaffolds in molecular probes for sensing and bio-imaging. Amphoteric nature of the benzimidazole
ring forms the basis of designing new fluorescent architectures for various metal ions, anions, nitroaromatics
as well as neutral organic molecules. Alongside, recent years have also witnessed the
emerging development of benzimidazole-based supramolecular gels, useful in sensing and water purification.
Supramolecular gels are a special class of self-assembled structures formed by weak noncovalent
interactions between the molecules and are easily tuned by external stimuli. Such stimuliresponsive
gels serve as smart materials because of their abilities to undergo gel-to-gel, or gel-to-sol
transition upon subtle change of the gel environment. Of various stimuli, ion coordination draws attention
for their visual detection and to adapt material properties. The ion-sensitive gels act as
fascinating biomaterials with potential applications in drug delivery, optoelectronics and catalysis.
Thus, designing of such ion-responsive gels is challenging. The rising popularity of benzimidazole
based-gels is related to its advanced properties such as π-bridging, hydrogen bonding, fluorescence
and ion coordinating abilities. This review focuses on recently developed various ion-responsive
benzimidazole motif-based supramolecular gelators by summarising the crucial role of the structural
parameters of benzimidazole gelators. Beside ion sensing, we also desire to summarize other possible
applications of gelators in material chemistry. Finally, the necessity and possibility of further exploration
of benzimidazole/ benzimidazolium derived gelators are briefly described.

Abstract
In this manuscript, a new colorimetric and fluorescent chemosensor (T) was designed and synthesized, it could successively detect Cu2+ and H2PO4- in DMSO/H2O (v/v=9:1, pH=7.2) buffer solution with high selectivity and sensitivity. When added Cu2+ ions into the solution of T, it showed a color changes from yellow to colorless, meanwhile, the green fluorescence of sensor T quenched. This recognition behavior was not affected in the presence of other cations, including Hg2+, Ag+, Ca2+, Co2+, Ni2+, Cd2+, Pb2+, Zn2+, Cr3+, and Mg2+ ions. More interestingly, the Cu2+ ions contain sensor T solution could recover the color and fluorescence upon the addition of H2PO4- anions in the same medium. And other surveyed anions (including F-, Cl-, Br-, I-, AcO-, HSO4-, ClO4-, CN- and SCN-) had nearly no influence on the recognition behavior. The detection limits of T to Cu2+ and T-Cu2+ to H2PO4- were evaluated to be 1.609×10-8M and 0.994×10-7M, respectively. In addition, the sensor T also could be served as a recyclable component and the logic gate output was also defined in sensing materials. The test strips based on sensor T were fabricated, which acted as a convenient and efficient Cu2+ and H2PO4- test kits.
