摘要： Primary, secondary (1°,2°) alkylethylenediamine- and alkylpropylenediamine-appended variants of metal-organic framework are provided for CO2 capture applications. Increasing the size of the alkyl group on the secondary amine enhances the stability to diamine volatilization from the metal sites. Two-step adsorption/desorption profiles are overcome by minimzing steric interactions between adjacent ammonium carbamate chains. For instance, the isoreticularly expanded framework Mg2(dotpdc) (dotpdc4−=4,4″-dioxido-[1,1′:4′,1″-terphenyl]-3,3″-dicarboxylate), yields diamine-appended adsorbents displaying a single CO2 adsorption step. Further, use of the isomeric framework Mg-IRMOF-74-II or Mg2(pc-dobpdc) (pc-dobpdc4−=3,3-dioxidobiphenyl-4,4-dicarboxylate, pc=para-carboxylate) also leads to a single CO2 adsorption step with bulky diamines. By relieving steric interactions between adjacent ammonium carbamate chains, these frameworks enable step-shaped CO2 adsorption, decreased water co-adsorption, and increased stability to diamine loss. Variants of Mg2(dotpdc) and Mg2(pc-dobpdc) functionalized with large diamines such as N-(n-heptyl)ethylenediamine have utility as adsorbents for carbon capture applications.

摘要： Compounds are synthesized with bicyclic amidinate ligands attached to one or more metal atoms. These compounds are useful for the synthesis of materials containing metals. Examples include pure metals, metal alloys, metal oxides, metal nitrides, metal phosphides, metal sulfides, metal selenides, metal tellurides, metal borides, metal carbides, metal silicides and metal germanides. Techniques for materials synthesis include vapor deposition (chemical vapor deposition and atomic layer deposition), liquid solution methods (sol-gel and precipitation) and solid-state pyrolysis. Copper metal films are formed on heated substrates by the reaction of copper(I) bicyclic amidinate vapor and hydrogen gas, whereas reaction with water vapor produces copper oxide. Silver and gold films were deposited on surfaces by reaction of their respective bicyclic amidinate vapors with hydrogen gas. Reaction of cobalt(II) bis(bicyclic amidinate) vapor, ammonia gas and hydrogen gas deposits cobalt metal films on heated substrates, while reaction with ammonia produces cobalt nitride and reaction with water vapor produces cobalt oxide. Ruthenium metal films are deposited by reaction of ruthenium(II) bis(bicyclic amidinate) or ruthenium(III) tris(bicyclic amidinate) at a heated surface either with or without a co-reactant such as hydrogen gas or ammonia or oxygen. Suitable applications include electrical interconnects in microelectronics and magnetoresistant layers in magnetic information storage devices. Hafnium oxide films are deposited by reaction of hafnium(IV) tetrakis(bicyclic amidinate) with oxygen sources such as water, hydrogen peroxide or ozone. The HfO2 films have high dielectric constant and low leakage current, suitable for applications as an insulator in microelectronics. The films have very uniform thickness and complete step coverage in narrow holes.

摘要： An industrially excellent production method for cycloalkyl(trifluoromethyl)benzene is free of complicated steps, small in the number of steps, and high in production efficiency. Cycloalkyl(trifluoromethyl)benzene is produced by reacting a halogen-substituted trifluoromethyl benzene with magnesium metal to produce a Grignard reagent and cross-coupling the Grignard reagent with a cycloalkyl halide in the presence of an iron salt or a cobalt salt at a reaction temperature of 60° C. to 80° C.
