“…The reaction was fast and was completed within a short time of 15 min. The synthesis, properties, and characterization of the polymers were communicated in our previous report [ 31 ]. The design of the material was executed to be advantageous for iodine capture properties by adding heteroatoms such as N, S, and O.…”

Organic polymers are widely explored due to their high stability, scalability, and more facile modification properties. We developed cost-effective dithiocarbamate-based organic polymers synthesized using diamides, carbon disulfide, and diamines to apply for environmental remediation. The sequestration of radioiodine is a serious concern to tackle when dealing with nuclear power for energy requirements. However, many of the current sorbents have the problem of slower adsorption for removing iodine. In this report, we discuss the utilization of an electron-rich dithiocarbamate-based organic polymer for the removal of iodine in a very short time and with high uptake. Our material showed 2.8 g/g uptake of vapor iodine in 1 h, 915.19 mg/g uptake of iodine from cyclohexane within 5 s, 93% removal of saturated iodine from water in 1 min, and 1250 mg/g uptake of triiodide ions from water within 30 s. To the best of our knowledge, the iodine capture was faster than previously observed for any existing material. The material was fully recyclable when applied for up to four cycles. Hence, this dithiocarbamate-based polymer can be a promising system for the fast removal of various forms of iodine and, thus, enhance environmental security.

Wastewater treatment has been bestowed with a plethora of materials; among them, metal−organic frameworks (MOFs) are one such kind with exceptional properties. Besides their application in gas adsorption and storage, they are applied in many fields. In orientation toward wastewater treatment, MOFs have been and are being successfully employed to capture a variety of aqueous pollutants, including both organic and inorganic ones. This review sheds light on the postsynthetic modifications (PSMs) performed over MOFs to adsorb and degrade recalcitrant. Modifications performed on the metal nodes and the linkers have been explained with reference to some widely used chemical modifications like alkylation, amination, thiol addition, tandem modifications, and coordinate modifications. The boost in pollutant removal efficacy, reaction rate, adsorption capacity, and selectivity for the modified MOFs is highlighted. The rationale and the robustness of micromotor MOFs, i.e., MOFs with motor activity, and their potential application in the capture of toxic pollutants are also presented for readers. This review also discusses the challenges and future recommendations to be considered in performing PSM over a MOF concerning wastewater treatment.

“…In dithiocarbamates, dithiocarbamic esters have been reported to have good interactions with various proteins and also with heavy metals. 21,22 With respect to biomedical applications, dithiocarbamates are also known to be strong potential candidates for antibacterial, 18 antifungal, 23 anticancer, 24 anti-trypanosomatid, 25 anti-lieshmanial, 16 and anti-inflammatory 26 agents. When appended onto macrocyclic structures, these dithiocarbamates have the added advantages of the features of both the macrocycle and the dithiocarbamate for their development as drugs for such applications.…”
