Abstract
Electrogenerated chemiluminescence (ECL) from films of the title compo unds in an electrolytic solution were studied. Poly(3-hexylthiophene) and poly(2-methoxy-5-dodecyloxy-p-phenylenevinylene) possess ECL predo minantly during the anodic and cathodic scan, respectively, in the dou ble potential step electrolysis which alternately produces negatively and positively charged excited species of the polymers. The chronoabso rptometric measurements indicated that the polarity dependence of the ECL is originated from the difference in the kinetics of the electroch emical p-and n-type doping/undoping reactions.
