Highly Fluorinated Porphyrins: From Ultra-Thin Films to Nanoparticles in Catalysis

Synthesis and Fluorescence Properties of Novel indol-3yl-thiazolo[3,2-a][1,3,5]triazines and indole-3-carbaldehyde Schiff Bases

“…In addition, materials with antioxidative property influence their photoconductance [7]. On the other hand, Nheterocycles also have been used as conducting materials, electrochemical sensors and photonics [8][9][10][11][12]. Their behavior has been determined by physiochemical characteristic studies such as solvatochromic, piezochromic, oscillator strength, dipole moment, fluorescent quantum yield and photostability.…”

Functionalization of SiC(110) Surfaces via Porphyrin Adsorption: Ab Initio Results

“…The periphery of the ring can be functionalized with a variety of substituents that modulate both the photophysical and the material properties. In particular, substitution with perfluoro-alkane moieties and perfluoro-phenyl groups improves their supramolecular self-organizing properties as well as the robustness of porphyrinic materials: the presence of fluorines tends to stabilize the molecular assemblies and increases charge transfer and reactivity, − along with their resistance toward oxidation …”

“…In particular, substitution with perfluoro-alkane moieties and perfluoro-phenyl groups improves their supramolecular self-organizing properties as well as the robustness of porphyrinic materials: the presence of fluorines tends to stabilize the molecular assemblies and increases charge transfer and reactivity, 12À14 along with their resistance toward oxidation. 15 On metal surfaces, adsorption of empty and metal-coordinated porphyrins decorated with different functional groups in the external rings has been thoroughly studied, 11,16 but very little is known on semiconductor surfaces, where different adsorption mechanisms may act, such as cycloaddition, πÀπ interaction, or formation of halogen bonds, depending on the charge distribution, bond ionicity, and polarity of the underlying substrate.…”
