    摘要: A poly(phenylene) compound of copolymers that can be prepared with either random or multiblock structures where a first polymer has a repeat unit with a structure of four sequentially connected phenyl rings with a total of 2 pendant phenyl groups and 4 pendant tolyl groups and the second polymer has a repeat unit with a structure of four sequentially connected phenyl rings with a total of 6 pendant phenyl groups. The second polymer has chemical groups attached to some of the pendant phenyl groups selected from CH3, CH2Br, and CH2N(CH3)3Br groups. When at least one group is CH2N(CH3)3Br, the material functions as an anion exchange membrane.

    摘要: A method for preparing a defunctionalized alkylenedioxyheterocycle polymer or copolymer involves providing a polycarboxylic acid derivative functionalized alkylenedioxyheterocycle polymer or copolymer and transforming the polymer or copolymer into a defunctionalized alkylenedioxyheterocycle polymer or copolymer which is a polyhydroxy, polythiol, polyamino, or polycarboxylic acid functionalized alkylenedioxyheterocycle polymer or copolymer. The monomers, homopolymers and copolymers for use in the method are new compositions of matter. The polymers containing polycarboxylic acid derivative functionalized alkylenedioxyheterocycle units are soluble polymers which are defunctionalized to yield insoluble polyhydroxy, polythiol, polyamino, or polycarboxylic acid functionalized alkylenedioxyheterocycle polymers. These polymers can be cast as films for use as: hole transport layers in organic light emitting diodes; active electrochrome in electrochromic windows, mirrors and displays; field effect transistors, supercapacitors, batteries, photovoltaic cells, and other electronic components; electronic paper; anti-stat conductors; and transparent conductors.

    摘要: The present invention relates to functionalized polymers including a poly(phenylene) structure. In some embodiments, the polymers and copolymers of the invention include a highly localized concentration of acidic moieties, which facilitate proton transport and conduction through networks formed from these polymers. In addition, the polymers can include functional moieties, such as electron-withdrawing moieties, to protect the polymeric backbone, thereby extending its durability. Such enhanced proton transport and durability can be beneficial for any high performance platform that employs proton exchange polymeric membranes, such as in fuel cells or flow batteries.
