A pharmaceutical hydrogen-bonded covalent organic polymer for enrichment of volatile iodine

Abstract

A pharmaceutical hydrogen-bonded covalent organic polymer (pha-HCOP-1) is constructed with the formation of two types of bonds using the pharmaceutical isoniazid as a bifunctional linker. The as-synthesised pha-HCOP-1 exhibits good adsorption ability for iodine molecules.

Adsorption Behavior of Iodine by Novel Covalent Organic Polymers Constructed Through Heterostructural Mixed Linkers

“…In recent years, POPs have been turned out the validity and feasibility of the appropriateness for solving environmental issues beyond their previous application in catalysis aspect, molecular recognition field and so on and so forth (Huang et al, 2017). Of particular success are the utilization to decontaminate various toxic and hazardous substances involving heavy metal ions and organic pollutants, of course, certainly with the efficient volatile iodine removal (Liao et al, 2016;Lin L. et al, 2017;Merí-Bof et al, 2017;Guo et al, 2018).…”

Constructing “breathing” dynamic skeletons with extra π-conjugated adsorption sites for iodine capture

“…2d). 55,56 All these results demonstrate the adsorbed I 2 molecules are uniformly distributed in the PAF architecture suggesting the dynamic conguration transformation of PAF skeleton for tting the I 2 storage.…”

“…This increased capacity is attributed to the exible skeleton provides sufficient space for the accessibility of iodine to p-conjugated groups which possess a strong affinity for guest binding through charge transfer. [55][56][57] Furthermore, two increased FT-IR peaks of conjugated group located at 1258 and 1159 cm À1 and the emerging Raman signals at 110 and 175 cm À1 demonstrate this charge transfer from the highest occupied molecular orbital (HOMO) of p-conjugated group to the lowest unoccupied molecular orbital (LUMO) of iodine. 45 As to LNU-4 (2.04 g g À1 iodine uptake), the anthracene constituent with a similar binding structure as naphthalene group increases the weight of structural unit resulting in the reduced maximum I 2 capacity compared with LNU-2 and LNU-3.…”

Polymer‐supported palladium (II) containing N2O2: An efficient and robust heterogeneous catalyst for C–C coupling reactions

“…Porous organic polymers are recognized in a broader sense as a new alternative class material after introduction of COF. These porous organic polymers are usually synthesized from one or two components via coupling or condensation reaction and obtained great attention because of their ease of synthesis, chemical and water stabilities, high specific surface areas, high thermal stability, and light weight . The catalysts (containing N 2 O 2 active center) synthesized via Schiff base reaction from the monomers of 1,3,5‐triformylphloroglucinol and amines have witnessed impressive progress for their applications in catalytic supports, electronic devices and energy storage, gas storage, anticancer agent, and water purification .…”
