Here we established a biomimetic high-flux protein delivery system via the introduction of the pillar[5]arene-based host–guest systems into one side of the hour-glass shaped nanochannels. With a transport flux of 660 lysozymes perminute, the system provides efficient high-flux protein transport at a rate which is significantly higher than that of an unmodified nanochannel and conventional bilateral

A phosphonated-functionalized copillar[5]arene was designed and synthesized. 1H NMR, 13C NMR, ESI-MS and HR-MS were performed to provide converging evidences of the structure of obtained copillar[5]arene. Driven by hydrophobic interactions and C–H···π interactions between the decyl moiety and the pillar[5]arene cavity, a pH-responsive linear supramolecularpolymer was fabricated from this phosphonate-functionalized
设计并合成了一种膦酸酯化的功能化copillar [5]芳烃。进行了1 H NMR,13 C NMR,ESI-MS和HR-MS,以提供所获得的Copillar [5]芳烃结构的融合证据。由癸基部分与柱[5]芳烃腔之间的疏水相互作用和CH-··π相互作用驱动,由这种膦酸酯官能化的AB型单体在水中制备pH响应的线性超分子聚合物。进行了浓度依赖性的1 H NMR,NOESY,DOSY和比粘度测定,以研究超分子聚合过程。

Side-chain functionalized poly(p-phenylene ethynylene)s (PPEs) carrying triazole linkers, amino donors/receptors, and solubilizing groups have been found to yield remarkably high efficiency of fluorescence turn-on sensing for Zn2+ and Cd2+ ions in THF, and for H+ and Cd2+ ions in water.

A series of phenylenebis(oxy)bis[2,2-dimethylpentanoic acid]s have been synthesized and evaluated as potential hypolipidemic agents. Compound 18 (CI-924) was found to be the most potent compound in this series. In rats, compound 18 not only reduced low-density lipoprotein cholesterol but also increased high-density lipoprotein (HDL) cholesterol. Comparative studies in rats indicated 18 produced an
