As eries of calix [4]pyrrole-based crosslinked polymer networks designed for iodine capture is reported. These materials were prepared by Sonogashira coupling of a,a,a,atetra(4-alkynylphenyl)calix [4]pyrrole with bishalide building blocks with different electronic properties and molecular sizes. Despite their low Brunauer-Emmett-Teller surface areas, iodine vapor adsorption capacities of up to 3.38 gg À1 were seen, af inding ascribed to the presence of al arge number of effective sorption sites including macrocyclic p-rich cavities, aryl units,a nd alkyne groups within the material. One particular system, C[4]P-BTP,was found to be highly effective at iodine capture from water (uptake capacity of 3.24 gg À1 from ac oncentrated aqueous KI/I 2 solution at ambient temperature). Fast capture kinetics (k obs = 7.814 gg À1 min À1 ) were seen. Flow-through adsorption experiments revealed that C[4]P-BTP is able to remove 93.2 %o fi odine from an aqueous source phase at aflow rate of 1mLmin À1 .

Calix[4]pyrrole-based porous organic polymers (P1-P3)f or removing organic micropollutants from water were prepared. Ab owl-shaped a,a,a,a-tetraalkynyl calix-[4]pyrrole and diketopyrrolopyrrole monomer were crosslinked via Sonogashira coupling to produce a3 Dn etwork polymer, P1. P1 proved too hydrophobic for use as an adsorbent and was converted to the corresponding neutral polymer P2 (containing carboxylic acid groups) and its anionic derivative P3 (containing carboxylate anion groups). Anionic P3 outperformed P2 in screening studies involving avariety of model organic micropollutants of different charge, hydrophilicity and functionality. P3 proved particularly effective for cationic micropollutants.T he theoretical maximum adsorption capacity (q max,e)o fP3 reached 454 mg g À1 for the dye methylene blue,344 mg g À1 for the pesticide paraquat, and 495 mg g À1 for diquat. These uptake values are significantly higher than those of most synthetic adsorbent materials reported to date.

We report here a set of fluorescent supramolecular organic frameworks (SOFs) that incorporate aggregationinduced emission (AIE) units within their frameworks. The fluorescent SOFs of this study were constructed by linking the tetraphenylethylene (TPE)-based tetra(amidinium) cation TPE 4 + and aromatic dicarboxylate anions through amidiniumcarboxylate salt bridges. The resulting self-assembled structures are characterized by fluorescence quantum yields in the range of 4.6 ~14 %. This emissive behavior is ascribed to a combination of electrostatic interactions and hydrogen bonds that operate in concert to impede motions that would otherwise lead to excited state energy dissipation. Singlecrystal X-ray diffraction analyses revealed that the length of the dicarboxylate anion bridges has a considerable impact on the structural features of the resulting frameworks. Nevertheless, all SOFs prepared in the context of the present study were found to display emissive features characteristic of TPEbased AIE luminogens with only a modest dependence on the structural specifics being seen. The SOFs reported here could be reversibly "broken up" and "reformed" in response to acid/base stimuli. This reversible structural behavior is consistent with their SOF nature.

Calix[4]pyrrole‐based porous organic polymers (P1–P3) for removing organic micropollutants from water were prepared. A bowl‐shaped α,α,α,α‐tetraalkynyl calix[4]pyrrole and diketopyrrolopyrrole monomer were crosslinked via Sonogashira coupling to produce a 3D network polymer, P1. P1 proved too hydrophobic for use as an adsorbent and was converted to the corresponding neutral polymer P2 (containing carboxylic acid groups) and its anionic derivative P3 (containing carboxylate anion groups). Anionic P3 outperformed P2 in screening studies involving a variety of model organic micropollutants of different charge, hydrophilicity and functionality. P3 proved particularly effective for cationic micropollutants. The theoretical maximum adsorption capacity (qmax,e) of P3 reached 454 mg g−1 for the dye methylene blue, 344 mg g−1 for the pesticide paraquat, and 495 mg g−1 for diquat. These uptake values are significantly higher than those of most synthetic adsorbent materials reported to date.
