Growth, characterization and sensing capabilities of 5,10,15,20-meso-tetraphenyl iron (III) porphyrin chloride films obtained by means of a novel plasma-based deposition technique

Physical Vapour Deposition Techniques for Producing Advanced Organic Chemical Sensors

“…As optical properties of porphyrin compounds can be affected by changes in the aggregation state, UV-Vis spectra give also information about the film structures: in particular the main differences between GDS and SPIN spectra (Q bands of the samples show different redshifting and both the B and Q bands show different broadening) clearly indicate different molecular arrangements within the two differently deposited Fe(TPP)Cl films (Tonezzer et al, 2009). In order to analyze the structures of differently deposited porphyrin films, several analyses were performed (Tonezzer, 2007c): among them SEM images give an important information about the samples morphology.…”

Plasma Polymer Membranes for Immobilising Metalloporphyrins

“…100 nm) strongly differs from the one of single porphyrin molecules (ca. 1 nm), which are likely to be chemically altered or undergo full cleavage of the macrocycle when exposed to inappropriate plasma conditions 24, 25. Moreover, in previous AP‐DBD studies, the aggregation of the particles was not a critical issue.…”

Interfacially polymerized metalloporphyrin thin films for colorimetric sensing of organic vapors

“…While electrostatically deposited thin films have demonstrated predictable and selective sensing upon the initial exposure of the sensor to an analyte, electrostatic attractions are easily overcome by exposing films to a suitable solvent, potentially resulting in film dissolution or reduced efficacy over repeated use, and a limited choice of analytes due to solubility concerns. Recently, several reports have focused on generating more structurally robust materials by using non-electrostatic deposition techniques including physical deposition methods [12,13], incorporation of the sensor in a polymeric matrix [14,15] and covalent bonding of monolayers to substrates [16].…”
