  Synthesis of Strained Macrocyclic Biaryls for Enthalpy-Driven Ring-Opening Polymerization

  摘要：

  Polymerizable macrocyclic biarylene-ether-ketones and biarylene-ether-sulfones are accessible from linear, bis(chloro)-terminated oligomers via nickel-catalyzed, intramolecular coupling under pseudo-high-dilution conditions. Single-crystal X-ray analyses of the resulting cyclo-oligomers reveal extremely distorted and highly strained geometries, with 4,4 '-biphenylene units showing deviations of up to 70 degrees from linearity.

  The invention relates to the preparation of a crosslinked polymeric film bearing ionic groupings. The process consists in extruding a material comprising at least one prepolymer, in polymerizing said material after extrusion, and in subjecting the extruded material to a chemical reaction for grafting ionic groupings. The prepolymer comprises repeating units each comprising at least one aromatic group GA and at least one functional group GF; it bears at least one group GP which is polymerizable thermally at a temperature greater than the extrusion temperature, or photochemically, and also at least one reactive group GR which allows the grafting of ionic groupings. The films are useful as a membrane for fuel cells or electrodialysis, as an electrolyte of a lithium battery, of a supercapacitor or of an electrochromic device, or as an ion exchange membrane.

  The present invention relates to an ion conducting polymer including a partially branched block copolymer; a method of preparing the same; an ion conductor including the ion conducting polymer; an electrolytic membrane including the ion conducting polymer; a membrane-electrode assembly comprising the electrolytic membrane, and a battery comprising the same; and a separation membrane for a redox flow battery including the ion conducting polymer, and a redox flow battery comprising same. Specifically, the partially branched block copolymer includes: a first block including a hydrophilic first polymer; a second block derived from a hydrophobic second polymer having two or more reactive groups respectively on its both ends, in such a way as to form branching points forming side branches on a main chain; and optionally a third block including a hydrophobic third polymer. The ion conducting polymer in the form of a partially branched block copolymer can prepare a polymer membrane having improved conductivity and superior physical properties such as tensile strength elongation at break, etc., while having the same or similar ion-exchange capacity (IEC), percentage water absorption and/or degree of dimensional change compared to conventional ion conducting polymers in the form of linear block copolymers. Because of such outstanding physical properties, the polymer membrane can be used as a membrane-electrode assembly for a fuel cell, and a redox flow battery comprising the same as a separation membrane can exhibit outstanding cell performance and maintain high discharge charge capacity retention rate even when repeatedly charged and discharged several times.
