摘要：

The chemical structure of polypyrrole (PPy) has been studied by 15N CPMAS NMR experiments on the 15N-labeled material. Only one broad line is found at about 120 ppm (external reference 15NH4Cl) which indicates that all nitrogen atoms of PPy are protonated. Thus, PPy is best described as a chain of linked pyrrole molecules. Two-dimensional NMR experiments show that the 15N line is inhomogeneously broadened. The width of the line is substantially larger in positively charged PPy. © 1990.
