Crown ether (CE)-based Li+ adsorbent microfibers (MFs) were successfully fabricated through a combined use of CE diols, electrospinning, and aerosol cross-linking. The 14- to 16-membered CEs, with varied ring subunits cavity dimensions, have two hydroxyl groups for covalent attachments poly(vinyl alcohol) (PVA) as the chosen matrix. diols blended PVA transformed into via highly effective technique in minimizing loss during MF fabrication. Subsequent glutaraldehyde (GA) cross-linking...
Abstract A series of 14‐15‐membered O, N, and S‐containing crown ethers (CEs) was synthesized by cyclization bis‐epoxides with aryl‐N or S dinucleophiles using triethylamine as a catalyst LiCl metal template in water. The dosage, type dosage were critical achieving yields 56–93 %. Liquid‐liquid extraction (LLE) performed to evaluate the CE complexation Pd 2+ Pt . Among CEs, dioxa‐dithia dibenzo exhibited highest selectivity even presence other platinum‐group metals (PGMs). Complementary DFT...
Herein, “knitted” tetrabenzo-24-crown-8 ether sulfonate (X-S-TB24CE8) was prepared to afford a practical hydrophilic Cs+ adsorbent. Cyclic TB24CE8 ligands were hyper-crosslinked with dimethoxymethane in the presence of template followed by sulfonation introduce -SO3- groups. Thorough characterization X-S-TB24CE8 using FTIR, TGA, EA, N2 adsorption/desorption, DLS, XPS, and SEM-EDX confirms that it is thermally stable nature. It possesses granulated porous structure can be easily recovered...
