Abstract
Metallocorrole derivatives are a versatile class of coordination complexes successfully exploited in different applications, ranging from medical to environmental fields, due to their peculiar tuneable properties. Herein, a novel class of conductometric sensing films has been deposited directly onto the interdigitated electrodes by the electropolymerization of metallocorroles and metalloporphyrins. Remarkably, not only can the chemical sensing properties be tuned by choice of central-coordination metal, but the electropolymerization protocol can also modulate the conductive nature of polymers (n- or p-type). Finally, the fabricated sensors were tested towards a large family of volatile compounds and gases, finding high sensitivity to nitrogen oxide also in the presence of a high humidity environment.
