Electrogenerated chemiluminescence of luminol on wireless conducting polymer films

Electrogenerated chemiluminescence of pure polymer films and polymer blends.

We recently reported the discovery of soliton-like electrogenerated chemiluminescence (ECL) waves from pure conjugated polymer films and gold-nanoparticles-doped polymer films. In addition to a more detailed study of these polymer systems by changing the film thickness and the distribution of local leaks, we also apply the ECL wave phenomenon to polymer blends of conjugated and nonconjugated po...

Flow-injection electrogenerated chemiluminescence determination of isoniazid using luminol.

Based on a new electrogenerated chemiluminescence (ECL) analytical idea, this paper explains a sensitive and selective flow-injection ECL method using luminol for the determination of isoniazid, based on the sensitizing effect of isoniazid for the weak ECL emission of electrochemically oxidized luminol. Under the optimum experimental conditions, the relative ECL intensity was linear with isonia...

Electrogenerated chemiluminescence of single conjugated polymer nanoparticles.

We demonstrate a novel and powerful method to study electrogenerated chemiluminescence (ECL) of single nanoparticles (NPs) (r = 25 +/- 15 nm) of a conjugated polymer, F8BT, on an ITO electrode in the presence of a co-reactant, such as tri-n-propylamine (TPrAH) in acetonitrile solution. The results reveal that the maximum formation rate of ECL of individual NPs is achieved after a long "build-up...

Sharp Fickian Behavior of Electrogenerated Chemiluminescence Waves in Conjugated Polymer Films

One technique to study electrochemical oxidation phenomena in thin polymer films is the generation of electrogenerated chemiluminescence (ECL) waves. Such waves are sharp and easy to image, and recent experiments have shown both constant-speed and Fickian-style wave behavior. One way to model such waves mathematically is to track the concentration of the ion clusters in the polymer film. One su...
