| Abstract: | Polymers containing 1,4-dihydronicotinamide (P-NAH) alloxan (P-A), and viologen (P-V2+) moieties were synthesized and characterized. P-NAH reduced various organic substances such as lipoic acid, alloxan, and viologens and also immobilized quinone mediated by alloxan. P-A was reduced to the polymer-bearing alloxan radical and the dialuric acid structure without crosslinks by one- and two-electron reduction, respectively, and P-A also mediated the redox reaction occurring between aqueous and organic (water-immiscible) layers. P-V2+ was converted to the stable viologen radical reversibly by one-electron reduction. Electric potentials and currents on photo-reduction of P-V2+ and catalytic behavior of P-V2+ in the reduction of carbonyl compounds were examined. |
