“…In the potentiodynamic ED, the electrode potential is varied during the deposition steps to achieve specific coating properties providing information about the ED mechanism cycleby-cycle [211]. In potentiodynamic mode, the supramolecular arrangement, including the morphology and thickness of the film, can be controlled by the deposition rate (scan rate) [212], the number of potential cycles, and the potential range. On the other hand, the potentiostatic ED maintains a constant electrode potential for a uniform and controlled deposition, and parameters such as applied potential and time can be controlled [10].…”

“…Due to their high supramolecular stabilization and adsorption on the conducting surfaces, these molecules have been used to create ED films for sensing and electrical devices [254][255][256][257]. The porphyrins also draw attention due to the possibility of their ED through the metal-free porphyrins [212,258]. Kusmin et al [258] demonstrated the effect of the substituents in porphyrins and investigated how the potentiostatic or potentiodynamic modes influence the film deposition, leading to changes in the supramolecular arrangement, including surface morphology and molecular structure [258].…”

In recent decades, many research efforts have been dedicated to finding highly sensitive devices for fast and reliable identification and quantification of an expanding range of analytes. As a result, there has been an increased number of publications dedicated to this area and a consequent increase in the number of review papers on the subject. However, unlike most review articles, we chose to explore the impact of supramolecular arrangement (or deeper, when possible, approaching the molecular organization) and assembly variables on sensing performance. This review briefly discusses the methods used to determine the molecular organization of thin films. We also examine various deposition techniques, including Langmuir-Blodgett, Langmuir-Schaefer, Layer-by-Layer assembly, electrodeposition, and spray pyrolysis, describing mainly (but not limited to) the advances in the last five years in developing thin films for sensors, with a particular emphasis on how the supramolecular arrangement can influence the sensing properties of these films.
