Porphyrin‐Based Nanostructures for Sensing Applications

Abstract: The construction of nanosized supramolecular hosts via self-assembly of molecular components is a fascinating field of research. Such intriguing class of architectures, beside their intrinsic intellectual stimuli, is of importance in many fields of chemistry and technology, such as material chemistry, catalysis, and sensor applications. Within this wide scenario, tailored solid films of porphyrin derivatives are structures of great potential for, among others, chemical sensor applications. The formation ofsupr… Show more

“…For G p + H 2 TPP complex, the highest value (i.e., lowest absolute value) of −41.72 kcal mol −1 was obtained at 0.005-Ha smearing, whereas decreasing the latter to 0.0001 Ha resulted in lowering the energy to −66.52 kcal mol −1 , which is essentially the same as the one of −66.59 kcal mol −1 obtained with Fermi occupation. On the contrary, the formation energies for G dt + H 2 TPP and G db +H 2 When changing the smearing from 0.005 to 0.0001 Ha, the HOMO-LUMO gap energies increased by ca. 10% for G p + H 2 TPP complex, decreased roughly by half for G dt + H 2 TPP, and remained almost unchanged for G db + H 2 TPP.…”

“…To date, there have been multiple reports on porphyrin-based self-assembled nanostructures with diverse architectures, namely rods, rings, sheets, wires, and tubes (see Ref. [2] and literature cited therein). An important fact is that in self-assemblies, the porphyrin units are held together and immobilized on the substrate by means of non-covalent interactions (i.e., hydrophobic, van der Waals, hydrogen bonding, -stacking, solvophobic and surface effects); resulting in the formation of the most thermodynamically stable structure, at the same time capable of rearrangements and * Author to whom correspondence should be addressed.…”

“…Porphyrins and their analogs are of considerable interest for researchers in the fields of biology, medicine, chemistry, optics and materials science because of their unique physical and chemical properties (Rovaldi et al 2000;Monti et al 2009;Wongsinkongman et al 2002). Different catalysts, sensors, drugs, organic semiconductors, liquid crystals and materials for nonlinear optics are created on the base of porphyrins (Drain et al 2002;Okura 2002;Guldi and Fukuzumi 2002).…”
