Pillar[n]arene-based supramolecular polymers have attracted great interest because of their tunable morphologies and external stimuli responsiveness. However, most the investigations previously reported were focused on formation transformation, applications are rare. Herein, we designed prepared hybrid polymeric materials by incorporating Pd nanoparticles into a polymer, constructed from pillar[5]arene dimer three-arm guest. The obtained polymer was fully characterized scanning electron...

Mechanically interlocked molecules are a class of smart supramolecular species because their interesting topological structure and application in various areas, such as biology nanoscience. In this work, we used "multicomponent reaction" to fabricate new [2]rotaxane based on pillar[5]arene from different small-sized molecules. The molecular the obtained R was confirmed by 1H 13C NMR, high-resolution electrospray ionization mass spectrometry, two-dimensional nuclear Overhauser effect...

Anaerobic dechlorination of chlorophenols often subjects to their toxicity and recalcitrance, presenting low loading rate poor degradation efficiency. In this study, in order accelerate p-chlorophenol (p-CP) reduction extracellular electron transfer an anaerobic system, three iron-oxide nanoparticles, namely hematite, magnetite ferrihydrite, were coupled into with the performance underlying role nanoparticles elucidated. The reductive p-CP was notably improved systems by hematite magnetite,...

The structure and composition of nanofillers have a significant influence on polyamide nanofiltration (NF) membranes. In this work, an asymmetric organic nanobowl containing concave cavity was synthesized incorporated into layer to prepare thin film nanocomposite (TFN) membranes via interfacial polymerization process. Benefiting from the hydrophilicity, hollow charge property compatible nanobowls, separation performance developed TFN membrane significantly improved. corresponding water...

Rationally designing membranes for efficient fractionation of dyes and salts is a great challenge in the membrane community. Here, composite loose nanofiltration (NF) was fabricated by depositing polyethylenimine (PEI) onto phosphomolybdic acid (PMo12)-loaded polyacrylonitrile substrate followed cross-linking with glutaraldehyde. The physical chemical properties NF were systematically investigated. Compared unloaded membrane, introduction PMo12 regulates deposition PEI, leading to smaller...
