Journal ArticleDOI
15N NMR of polyaniline
A.F. Richter,Anjan Ray,K.V. Ramanathan,Sanjeev K. Manohar,G.T. Furst,S.J. Opella,Alan G. MacDiarmid,Arthur J. Epstein +7 more
TL;DR: In this article, the leuco and emeraldine base forms of polyaniline were investigated using 15 N NMR spectroscopy and it was shown that emeraldines exist as an alternating copolymer of oxidized and reduced units.
Journal ArticleDOI
The Metallic State of Conducting Polymers: Microwave Dielectric Response and Optical Conductivity
A. J. Epstein,Jinsoo Joo,R. S. Kohlman,Alan G. MacDiarmid,J. M. Weisinger,Y. Min,Jean-Paul Pouget,Jun Tsukamoto +7 more
TL;DR: In this paper, the temperature (T) dependent microwave frequency dielectric constant, dc conductivity, and Kramers-Kronig analysis of conducting polyaniline and polyacetylene were presented.
Journal ArticleDOI
Transport and optical properties of polythiazyl bromides: (SNBr0.4)x
G.K. Chiang,Marshall J. Cohen,Dale L. Peebles,A. J. Heeger,M. Akhtar,J. Kleppinger,Alan G. MacDiarmid,JoAnn Milliken,M.J. Moran +8 more
TL;DR: The average room temperature conductivity of (SNBr0.4)x is 3.8 × 104 (ω-cm)-1 with temperature dependence characteristics of metallic behavior as mentioned in this paper.
Journal ArticleDOI
Aggregation and molecular conformation of doped polyaniline in chloroform solution
TL;DR: In this article, it was shown that both the freshly-made and aged chloroform solutions are comprised of doped polyaniline, the former containing aggregates (due to H-bonding) of single molecules having larger hydrodynamic volumes than the polyaniniline comprising the major peak.
Journal ArticleDOI
‘Organic metals’. New classes of p-type dopants for converting polyacetylene, (CH)x into the ‘metallic’ state
TL;DR: In this article, two new classes of dopants are introduced to give golden, flexible polyacetylene films exhibiting high conductivities characteristic of the metallic state, i.e., poly(CH)x.
