Porphyrin-containing polyimide films deposited by high vacuum co-evaporation

Singlet oxygen generating nanolayer coatings on NiTi alloy for photodynamic application

“…It indicates that PtCP molecules are still present on the surface of Al 2 O 3 coatings even after being washed by toluene solvent. In particular, both samples show the intense peaks at 700, 752, 798, 1073 and 3054 cm − 1 assigned to (C-H) stretching vibrations of phenyl and pyrrole rings [20][21][22]. Comparing FT-IR spectra of the pure PtCP and the PtCP functional nanolayer coatings, the pure PtCP has peaks at 3433 and 1687 cm − 1 corresponding to a hydroxyl and carbonyl stretching of the carboxyl groups of PtCP.…”

Luminescent solar concentrators employing new Eu(TTA)3phen‐containing parylene films

“…The data demonstrated that Eu(TTA) 3 phen compound can be sublimated in coarse vacuum and that the deposition rate is strongly influenced by the crucible temperature increasing more than 2.5 times when temperature increases from 172 to 178 °C. The deposition rate as a function of the crucible temperature can be fit by the following function : where D is the deposition rate expressed in moles cm −2 s −1 , T is the absolute temperature expressed in K, and A and B are constants determined by the fits and value, respectively 18 and 1.3 × 10 4 K.…”

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

“…Tetraphenyl porphyrins have assumed a peculiar role in different fields of disciplines, ranging from molecular semiconductors [7] to non-linear optics [8]: in particular several features, such as chemical and thermal stability, make porphyrins eligible as promising materials for gas sensing applications. For this reason, in the last years a great number of researchers has been interested in the exploitation of porphyrins and related macrocycles for the development of chemical sensors: great attention has been paid to the study of solid porphyrin films able to detect gases and volatile organic compounds (VOCs) [9][10][11][12][13][14][15][16][17]. Here we investigate the optical sensing capabilities of 5,10,15,20-meso-tetraphenyl iron (III) porphyrin chloride Fe(TPP)Cl towards ethanol.…”

“…Moreover, physical techniques, being dry techniques, produce solid films without using any extraneous compounds (i.e. chemical solvent) and allow to obtain samples characterized by very high purity [21,10]. Sample purity plays a basic role in the gas sensing field: in fact the presence of retained solvent, which represents a frequent drawback in organic films produced through standard chemical methods, can hinder partially the interaction between the film and the analyte molecules [22].…”
