Flavin-containing polyanion

Electrochemically Prepared Polyelectrolyte Complex of Polypyrrole and a Flavin-Containing Polyanion... 

Cycling of the PPy-film through its reduced and oxidized state does not lead to any loss of the flavin containing polyanion. In the case of low molar mass flavin-containing dopants most of the flavin is released from the film upon reduction of the PPy. 

Influence of polymerization conditions upon incorporation of flavin-containing polyanion. The amount of polyanion (1) incorporated as dopant in a PPy film during electropolymerization can easily be controlled by changing the ionic strength (low molar mass salt) and/or the pH of the monomer solution. The correlation between the amount of polymer-bound flavin incorporated in the film and the concentration of the added low molar mass salt, sodium-p-toluenesulphonate (NaOTs), at pH=7 is shown... 

The incorporated flavin-containing polyanions are immobilized very efficiently in the polypyrrole film. Figure 10 shows the current response curve of PPy-films doped with polymer (1) or with a low molar mass species, 3-(p-methylbenzoic acid)-7,8,10-trimethylisoalloxazine (2) respectively, for a freshly prepared film and for a PPy-film...
