Isoperimetric Quotient for Fullerenes and Other Polyhedral Cages
The notion of Isoperimetric Quotient (IQ) of a polyhedron has been already introduced by Polya. It is a measure that tells us how spherical is a given polyhedron. If we are given a polyhedral graph it can be drawn in a variety of ways in 3D space. As the coordinates of vertices belonging to the same face may not be co-planar the usual deenition of IQ fails. Therefore, a method based on a proper...
متن کاملMesoporous polyhedral cages and shells formed by textured self-assembly of ZnO nanocrystals.
We report a new structure, mesoporous structured polyhedral drum and spherical cages and shells formed by textured self-assembly of ZnO nanocrystals, which are made by a novel self-assembly process during epitaxial surface oxidation. The cages/shells exhibit unique geometrical shapes, and their walls are composed of mesoporous and textured ZnO nanocrystals. The structures of the cages and shell...
متن کاملStructure determination of neutral MgO clusters--hexagonal nanotubes and cages.
Structural information for neutral magnesium oxide clusters has been obtained by a comparison of their experimental vibrational spectra with predictions from theory. (MgO)(n) clusters with n = 3-16 have been studied in the gas phase with a tunable IR-UV two-color ionization scheme and size-selective infrared spectra have been measured. These IR spectra are compared to the calculated spectra of ...
متن کاملHomochiral Emissive Λ8‐ and Δ8‐[Ir8Pd4]16+ Supramolecular Cages
Synthetic self-assembly is a powerful technique for the bottom-up construction of discrete and well-defined polyhedral nanostructures resembling the spherical shape of large biological systems. In recent years, numerous Archimedean-shaped coordination cages have been reported based on the assembly of bent monodentate organic ligands containing two or more distal pyridyl rings and square-planar ...
متن کاملConstruction of tetrahydrofurans by PdII/PdIV-catalyzed aminooxygenation of alkenes.
Catalytic transformations involving Pd s-alkyl or s-aryl intermediates are widely used in organic synthesis and offer attractive routes to many valuable products. However, the vast majority of these reactions proceed by Pd/Pd mechanisms. As a result, the diversity of structures/bonds that can be constructed is constrained by the limitations of this redox cycle. Recent studies have explored the ...
