Their structures were determined by IR, H-1/C-13-NMR, MS spectra, and the crystal structure of 8 was further defined by X-ray diffraction.展开更多

The polymer was examined by UV-Vis, IR and NMR spectrometries. It possessed pi-conjugated backbone in the main chain. No significant variation in the electrical conductivity of BF3-doped PETFB was observed after more than three months' storage, indicating improved conductive stability in air as compared with polyacetylene.展开更多
