摘要：

Protonation of poly [C-hydroxyl-(4-N-dimethylamino)phenyl]dithienylmethine with (IS)-(+)-10-camphorsulfonic acid (CSA) induced a structural change on the pendant group of the polymer and resulted in the formation of a cationic quinoid iminium moiety. This chemical transformation changed the polymer from a non-conducting polymer into a semi-conducting polymer with the maximum ionic conductivity of 2 x 10(-4) S cm(-1) at 10 mol% CSA-doping level. The polydithienylmethines doped with various CSA loadings were characterized by UV-vis-NIR, FF-IR and Raman spectroscopy. An ion-hopping mechanism was suggested as the conduction mechanism for this CSA-doped polymer. (c) 2006 Elsevier B.V. All rights reserved.
