摘要:A method is for the synthesis of an array of metal nanowires (w) capable of supporting localized plasmon resonances. A metal film (M) deposited on a planar substrate (D) is irradiated with a defocused beam of noble gas ions (IB) under high vacuum, so that, with increasing ion doses a corrugation is produced on the metal film surface, formed by a mutually parallel nanoscale self-organized corrugations (r). Subsequently, the height of the self-organized corrugations peaks is increased relative to the valleys (t) interposed therebetween. Then the whole the metal film is eroded so as to expose the substrate at the valleys, and to mutually disconnect the self-organized corrugations, thereby generating the array of metal nanowires. Finally, the transversal cross-section of the nanowires is reduced in a controlled manner so as to adjust the localized plasmon resonances wavelength which can be associated thereto. The nanowires array constitutes an electrode of an improved photonic device.

标 题:Process for the preparation of 9-β-anomeric nucleoside analogs

摘要:A process for substantially enhancing the regio and stereoselective synthesis of 9-β-anomeric nucleoside analogs is described. The introduction of the sugar moiety onto a 6-substituted purine base was preformed so that only the 9-β-D- or L-purine nucleoside analogs were obtained. This regio and stereoselective introduction of the sugar moiety allows the synthesis of nucleoside analogs and in particular 2′-deoxy, 3′-deoxy, 2′-deoxy-2′-β-fluoro and 2′,3′-dideoxy-2′-β-fluoro purine nucleoside analogs in high yield without virtually any formation of the 7-positional isomers. The compounds are drugs or intermediates to drugs.

摘要:The present invention is relates to the synthesis of predominantly planar heterocyclic organic compound and the manufacture of optical films based on these compounds. Said organic compound has the general structural formula where Het is a predominantly planar heterocyclic molecular system possessing hydrophilic properties; B is a binding group; p is the number in the range from 3 to 8; S is a group providing solubility of the organic compound; m is a number in the range from 0 to 8. Said organic compound is transparent for electromagnetic radiation in the visible spectral range from 400 to 700 nm, and a solution of the compound or a salt thereof is capable of forming a substantially transparent optical layer on a substrate, with the heterocyclic molecular planes oriented predominantly parallel to the substrate surface.
