Influence of the Substitution Pattern of Cp-Iron-Arene Salts in the Solid-State Synthesis of New Carbon Nanostructures

Abstract

A series of Cp-iron-arene hexafluorophosphate salts have been prepared and pyrolyzed under autogenous pressure. It was found that the resulting carbon nanostructures were highly dependent on the starting material. Even a small change in the substitution pattern of the arene ligand could result in different material. In addition to very short hollow carbon nanofibers, also called carbon nanocapsules, it was possible to prepare long homogeneous carbon fibers in quantitative yield, which incorporated iron phosphorus composite particles in remarkable continuous distances.
