Patent number: 9382618Abstract: A method for synthesizing an In(III) N,N?-diisopropylacetamidinate precursor including cooling a mixture comprised of diisopropylcarbodiimide and diethyl ether to approximately ?30° C., adding methyllithium drop-wise into the mixture, allowing the mixture to warm to room temperature, adding indium(III) chloride as a solid to the mixture to produce a white solid, dissolving the white solid in pentane to form a clear and colorless solution, filtering the mixture over a celite plug, and evaporating the solution under reduced pressure to obtain a solid In(III) N,N?-diisopropylacetamidinate precursor. This precursor has been further used to develop a novel atomic layer deposition technique for indium sulfide by dosing a reactor with the precursor, purging with nitrogen, dosing with dilute hydrogen sulfide, purging again with nitrogen, and repeating these steps to increase growth.Type: GrantFiled: July 18, 2014Date of Patent: July 5, 2016Assignee: UChicago Argnonne, LLCInventors: Alex B. Martinson, Adam S. Hock, Robert McCarthy, Matthew S. Weimer

Patent number: 9242240Abstract: The present invention provides methods for the synthesis of catalysts and precursors thereof. Methods of the invention may comprise combining a catalyst precursor and at least one ligand to generate a catalytically active species, often under mild conditions and in high yields. In some cases, a wide variety of catalysts may be synthesized from a single catalyst precursor. Methods of the invention may also include the preparation of catalysts which, under reaction conditions known in the art, may have been difficult or impossible to prepare and/or isolate due to, for example, steric crowding at the metal center. The present invention also provides catalyst compositions, and precursors thereof, which may be useful in various chemical reactions including olefin metathesis. In some cases, methods of the invention may reduce the number of synthetic and purification steps required to produce catalysts and/or other reaction products, as well as reducing time, cost, and waste production.Type: GrantFiled: September 8, 2014Date of Patent: January 26, 2016Assignee: Massachusetts Institute of TechnologyInventors: Adam S. Hock, Richard R. Schrock

Patent number: 8796483Abstract: Novel cyclic amides containing tin or lead are disclosed. These cyclic amides can be used for atomic layer deposition or chemical vapor deposition of tin or lead as well as their oxides, sulfides, selenides, nitrides, phosphides, carbides, silicides or borides or other compounds. Tin(IV) oxide, SnO2, films were deposited by reaction of a cyclic tin amide vapor and H2O2 or NO2 as oxygen sources. The films have high purity, smoothness, transparency, electrical conductivity, density, and uniform thickness even inside very narrow holes or trenches. Deposition temperatures are low enough for thermally sensitive substrates such as plastics. Suitable applications of these films include displays, light-emitting diodes, solar cells and gas sensors. Doping SnO2 with aluminum was used to reduce its conductivity, making material suitable as the active semiconductor layer in electron multipliers or transparent transistors.Type: GrantFiled: March 31, 2011Date of Patent: August 5, 2014Assignee: President and Fellows of Harvard CollegeInventors: Roy G.
