Abstract:	摘要： Various substituted dioxythiophenes bearing 3,4-propylenedioxythiophenes (ProDOT) and 3,4-ethylenedioxythiophene (EDOT) moieties successfully undergo Pd-catalyzed direct C–H arylation to yield π-conjugated polymers. The effects of palladium catalysts, phosphine ligands or additives, and functional groups on this facile polycondensation approach are investigated. Polymers from alkoxy-substituted ProDOT are synthesized with reasonable molecular weight (M n = 6100–9600) and low PDI (1.3–1.9). Four substituted EDOT with alkoxy or protected functional groups also undergo direct C–H arylation polycondensation to yield corresponding polymers. The obtained polydioxythiophenes exhibit UV–vis absorptions ranging from 480 to 590 nm, and these conjugated polymers are electroactive and reversibly switched between the oxidized and neutral states upon applying potentials. 其他題名： Macromolecules 出版者： Washington, DC: American Chemical Society 出版日期： 2012-10-09 出處： Macromolecules, 2012-10, Vol.45 (19), p.7783-7790 資源來源： American Chemical Society Journals 版權： Copyright © 2012 American Chemical Society 版權： 2015 INIST-CNRS 識別號： ISSN: 0024-9297 識別號： ISSN: 1520-5835 識別號： EISSN: 1520-5835 識別號： DOI: 10.1021/ma300719n 識別號： CODEN: MAMOBX
