Electrogenerated Films of Carbazole- and Thiophene-Based Microporous Polymer Networks

Electrochemical oxidative polymerization of rigid, multifunctional monomers allows for the generation of microporous thin films with high surface areas. In this work, multifunctional carbazole- and thiophene-based rigid monomers were utilized as tridimensional building blocks (tectons) toward the electrogeneration of microporous polymer films. The monomer structure plays an essential role on the properties of the resulting microporous polymer networks. A distinct correlation is observed between the number of electroactive substituents in the monomers and the specific surface area of the corresponding microporous polymer films. Potential applications were explored for the chemical and electrochemical detection of nitroaromatic compounds using optimized microporous polymer films.
