摘要

Novel electroactive conjugated network of poly(ethylene oxide) grafted polycarbazole freestanding film poly[ poly(N-epoxypropyl carbazole)] (PPEPC) was successfully achieved via anionic ring-open polymerization of N-epoxypropyl carbazole (EPC) and subsequently electrochemical polymerization of the resulting poly(N-epoxypropyl carbazole) (PEPC) in CH2Cl2-Bu4NPF6. Both doped and dedoped PPEPC films were partly soluble in strong polar solvents, such as dimethyl sulfoxide. In particular, remarkable enhancement of the fluorescence properties of dedoped PPEPC was observed in comparison with PEPC, and it was a good blue-light-emitter with maximum emission at 412 nm both in solution and solid state. Furthermore, the prepared PPEPC manifested favorable thermal stability and good mechanical properties, which can be easily bent or cut into variety of shapes. Scanning electron microscopy clearly showed that highly homogeneous PPEPC was formed on the electrode surface.
