摘要:Provided are β-cyc-assisted synthesis of an In-V group quantum dot, and a synthesis method therefor and the use thereof. The method for β-cyc-assisted synthesis of an In-V group quantum dot comprises: preparing a β-cyc-containing precursor solution of an In source and a V group element source, and subjecting it to a hydrothermal reaction; extracting a stock solution after the hydrothermal reaction by using an organic solvent; removing β-cyc from the stock solution, washing same with water and then extracting same; and heating and concentrating same to obtain a high-concentration In-V group quantum dot solution. With regard to the β-cyc-assisted synthesis of an In-V group quantum dot, the In-V group quantum dot synthesized with the assistance of β-cyc is prepared by using the method for β-cyc-assisted synthesis of an In-V group quantum dot. The use of β-cyc-assisted synthesis of an In-V group quantum dot is the use of the β-cyc-assisted synthesis of an In-V group quantum dot in the field of photovoltaics, and the field of photovoltaics comprises solar cells, photoelectrochemical hydrogen production and photoelectric detectors. Compared with traditional synthesis methods, this synthesis method has the advantages of green and environmentally friendly raw materials, a simple and safe process, a simple and convenient device, efficient and economic synthesis, and being low cost.

摘要:Sonochemical synthesis methods of particles (e.g., nanoparticles, microparticles, quantum dots) in emulsion reaction mixtures are described herein. The methods allow for control of the bulk temperature of the reaction mixtures to minimize the effects of solvent temperature increases. The sonochemical synthesis methods (e.g., in emulsion reaction mixtures) offer efficient, accelerated, and controllable pathways towards the on-demand synthesis of complex materials.

摘要:In the synthesis of ascofranone, a compound represented by formula (III), (IV), (V) or (VII) or an optical isomer thereof is used as an intermediate for the synthesis. [In the formulae, R 1 and R 2 independently represent a hydrogen atom, a C 1-7 alkyl group, a phenoxyalkyl group having a halogen atom on a carbon atom in a benzene ring therein, or a phenyl group having a C 1-7 alkoxy group or a C 1-7 alkoxycarbonyl group on a carbon atom in a benzene ring therein; and X represents a halogen atom or a group R 5 SO 3 (wherein R 5 represents a C 1-7 alkyl group or a phenyl group having a C 1-7 alkyl group on a carbon atom in a benzene ring therein).] By using the compound, it becomes possible to reduce the number of steps required for the total synthesis of ascofranone to 7 or 8 from 12 which is a number of the steps required for the conventional ascofranone total synthesis processes.

摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.
