Publication number: 20110015349Abstract: According to an aspect of the present invention, a method is provided in which a double diphenylethylene compound is reacted with a polymer that contains a carbocationically terminated chain thereby providing a 1,1-diphenylene end-functionalized chain. Subsequently, an alkylating agent is reacted with the 1,1-diphenylene end-functionalized chain, thereby providing an alkylated 1,1-diphenylene end-functionalized chain. In some embodiments, the method further comprises (a) optionally combining a 1,1-diphenylorganolithium compound with the alkylated 1,1-diphenylene end-functionalized polymer followed by (b) reacting an organolithium compound with the alkylated 1,1-diphenylene end-functionalized polymer. This provides an anionically terminated polymer, which can be used, for example, in subsequent anionic polymerization and coupling reactions.Type: ApplicationFiled: February 2, 2010Publication date: January 20, 2011Applicant: University of Massachusetts LowellInventors: Rudolf Faust, Jae Cheol Cho

Patent number: 7708908Abstract: An electroconductive carboxylic acid functionalized monomer corresponding to Formula (I), wherein A represents a hydrogen or a carboxyl group. Polymerized monomers of Formula (I) conjugated with a biomolecule result in conjugated PEDOT polymers of Formula (III) wherein A is a hydrogen or a carboxylic acid group and B is a biomolecule selected from the group consisting of a peptide, a protein, a lipid, a carbohydrate and a polynucleotide. The biomolecule conjugated polymers can be disposed onto an electrically conductive substrate wherein the substrate has a first layer of PEDOT polymerized on a surface of the substrate and a second layer of biomolecule conjugated PEDOT polymer of Formula (III) polymerized on the first layer of PEDOT. The first and second layers form a charge transport material in electrical communication with the conductive substrate. The electrically conductive substrate further comprises a dopant.Type: GrantFiled: February 27, 2008Date of Patent: May 4, 2010Assignee: The Regents of The University of MichiganInventors: Jinsang Kim, Jae Cheol Cho, Laura K.
