Porous materials have recently attracted much attention owing to their fascinating structures and broad applications. Moreover, exploring novel porous polymers affording the efficient capture of iodine is of significant interest. In contrast to the reported porous polymers fabricated with small mol. blocks, we herein report the preparation of porous polymer frameworks using rigid polyisocyanides as building blocks. First, tetrahedral four-arm star polyisocyanides with predictable mol. weight and low dispersity were synthesized; the chain-ends of the rigid polyisocyanide blocks were then crosslinked, yielding well-defined porous organic frameworks with a designed pore size and narrow distribution. Polymers of appropriate pore size were observed to efficiently capture radioactive iodine in both aqueous and vapor phases. More than 98% of iodine could be captured within 1 min from a saturated aqueous solution (capacity of up to 3.2 g g-1), and an adsorption capacity of up to 574 wt% of iodine in vapor was measured within 4 h. Moreover, the polymers could be recovered and recycled for iodine capture for at least six times, while maintaining high performance. In the experiment, the researchers used many compounds, for example, (Chloromethanetriyl)tribenzene (cas: 76-83-5Quality Control of (Chloromethanetriyl)tribenzene).
(Chloromethanetriyl)tribenzene (cas: 76-83-5) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Quality Control of (Chloromethanetriyl)tribenzene
