摘要:Low-temperature organometallic nucleation and crystallization-based synthesis methods for the fabrication of semiconductor and metal colloidal nanocrystals with narrow size distributions and tunable, size- and shape-dependent electronic and optical properties. Methods include (1) forming a reaction mixture in a reaction vessel under an inert atmosphere that includes at least one solvent, a cationic precursor, an anionic precursor, and at least a first surface stabilizing ligand while stirring at a temperature in a range from about 50° C. to about 130° C. and (2) growing nanocrystals in the reaction mixture for a period of time while maintaining the temperature, the stirring, and the inert-gas atmosphere.

标 题 :Process for the dimerization of hexafluoropropene oxide
发明人：KUEHNE GERHARD
权利人:HOECHST AG
摘要:In the dimerization of hexafluoropropene oxide to give oligomeric acid fluorides of the formula the ratio of the oligomeric constituents formed is directed, in an improved manner, towards the formation of the dimer (n=0) if the reaction is carried out in the presence of a catalyst system which consists of a mixture of a copper (I) compound and a copper (II) compound mixed with a complex-forming agent from the group of the nitriles, isocyanides, tertiary phosphines and cyclic hydrocarbons with 6 to 12 ring atoms and 2 to 3 double bonds in the ring, and an aprotic organic solvent. The dimer is an intermediate product in the synthesis of perfluoropropyl perfluorovinyl ether, the latter being employed as a comonomer in fluorine-containing copolymers.

摘要:Ternary and quaternary Chalcopyrite CuInxGa1-xSySe2-y (CIGS, where 0≰x and y≰1) nanoparticles were synthesized from molecular single source precursors (SSPs) by a one-pot reaction in a high boiling solvent using salt(s) (i.e. NaCl as by-product) as heat transfer agent via conventional convective heating method. The nanoparticles sizes were 1.8 nm to 5.2 nm as reaction temperatures were varied from 150° C. to 190° C. with very high-yield. Tunable nanoparticle size is achieved through manipulation of reaction temperature, reaction time, and precursor concentrations. In addition, the method developed in this study was scalable to achieve ultra-large quantities production of tetragonal and quaternary Chalcopyrite CIGS nanoparticles.
