  Cyclocondensations of aromatic diamines with 1,1′-bis(2,4-dinitrophenyl)-4,4′-bipyridinium salts afford doubly or quadruply charged, macrocyclic, N,N′-diarylbipyridinium cations. These are tolerant of a wide range of acids, bases, and nucleophiles, although they appear to undergo reversible, one-electron reduction by tertiary amines. Single-crystal X-ray analysis demonstrates the presence of a macrocycle

  芳香族二胺与1,1'-双（2,4-二硝基苯基）-4,4'-联吡啶鎓盐的环缩合可提供双电荷或四联电荷的大环N，N'-二芳基联吡啶鎓阳离子。它们可以耐受多种酸，碱和亲核试剂，尽管它们似乎受到叔胺的可逆单电子还原。单晶X射线分析表明存在大环构象，其中4,4'-联吡啶鎓和4,4'-联苯二磺酰基残基适当间隔并排列以与π-供体芳烃络合，并且在溶液中进行NMR研究确认与1,5-双[羟基（乙氧基）乙氧基]萘结合。

  A process for preparing multicomponent gas separation membranes is disclosed. The process involves casting two or more solutions of polymer, and partially removing solvent from the side of the cast polymer that is to form the gas separation layer of the membrane. The membrane is then quenched to freeze its structure and then the remainder of the solvent removed to form the gas separation membrane.

  Membranes are used to separate fluids for the production of oxygen-enriched air, nitrogen-enriched-air, for the separation of carbon dioxide from hydrocarbons, and the separation of hydrogen from various petrochemical and oil refining streams. Membranes are discussed that provide a resistance to interaction with process components or contaminants, which can lead to plasticizing of the membrane, while providing the mechanical strength required to withstand high membrane differential pressures and high process temperatures. Membranes of blended polymers are used to improve the mechanical strength of the polymers used to make separation membranes. Specifically, polyimide polymers are combined with a blend polymer that is a polyamide and/or a polyamide-imde polymer. The resulting polymer mix is used to produce various forms of high strength, chemically resistant membranes, including hollow-fiber membranes that are suitable for high pressure, high temperature applications.

  膜用于分离流体，以生产富氧空气和富氮空气，从碳氢化合物中分离二氧化碳，以及从各种石化和炼油流中分离氢气。所讨论的膜可抵御与工艺成分或污染物的相互作用（这可能导致膜的塑化），同时提供承受高膜压差和高工艺温度所需的机械强度。混合聚合物膜用于提高用于制造分离膜的聚合物的机械强度。具体来说，聚酰亚胺聚合物与聚酰胺和/或聚酰胺-酰亚胺聚合物的混合聚合物相结合。由此产生的聚合物混合物可用于生产各种形式的高强度、耐化学腐蚀膜，包括适用于高压、高温应用的中空纤维膜。
