A soft template approach to various porous nanostructures from conjugated carbazole-based monomers

We show that the shape of surfaces nanostructures is highly dependent on the amount of water present in the organic solvent and on the molecular structure of the carbazole monomers

Scholarcy highlights

  • Controlling the size and the shape of nanostructures on surfaces is fundamental for various applications while the formation of porous structures such as nanotubes is difficult
  • The monomer has a huge influence on nanostructure shape
  • The templateless electropolymerization is a choice process that forms nanostructured surfaces, and can tune their morphologies using different monomers. We used this soft-template and surfactant free electropolymerization in organic solvent to deposit for the first time carbazole-based monomers
  • We show that the shape of surfaces nanostructures is highly dependent on the amount of water present in the organic solvent and on the molecular structure of the carbazole monomers
  • Different morphologies are obtained from fibers to vertically aligned nanotubes and even porous membranes, depending on the monomer and on the electropolymerization method
  • The nanostructured surfaces reach superhydrophobic properties and their dynamical non-wetting behavior varies with the monomer and the electrochemical parameters
